The Nth Term of Quadratic Sequences 

Bro made me understand the topic in 9 minutes more than my teacher in 2 weeks

BROO your voice is so sick and you actually helped me just do the math without all the bollocs so i can pass the test, cheers dude

I have a huge exam coming up and this helped me so much, my maths teacher is terrible she makes it sound so complicated and I didn’t understand it at all

I have a test tomorrow and literally had no clue how to do this but by the end of this I understand fully! Thanks for all your help! Subscribing

I need to go to sleep, but I just remembered I have a maths test tomorrow 😪

I watched a shit ton of videos but this one is actually a video I can understand and not some gibberish. I'm preparing for a major exam so this really helped. Thank you so much

binge watching loads of these videos the night before my non-calc. maths gcse paper - you might save my grade!!!

I watched sooooo many of these videos but for some reason I understood yours☺

I appreciate the effort you put into making this, I now understand the format of these types of questions. Thank you & I wish you well.

i feel extreme affection towards u actually i love u

bro u explained it better in 1 video than my teacher ever could

Reading the comments, I see a few people getting confused on the last question where we "+1" so allow me to elaborate. The reason the last part is "-2n+1", and not "-2n-1". The "+1" , allow me to explain: -1, -3, -5, -7, -9 We evaluate our sequence and observe how it's moving. The sequence is moving in the negative times 2 pattern so: -2, -4, -6, -8, -10 Now lets write them both together, -1, -3, -5, -7, -9

Thank you so much for the explanation, my teacher explained it terribly and I have a test tomorrow. If i hadn't found your video, i would be absolutely stuffed. You are an absolute genius!

my teach taught this to me in year 9. i was top set, and pretty lazy, so my attention span those lessons was... lackiing. Ever since, its been coming up in tests. end of topics, end of years, and i've just been crawling along, no sense of direction with the method. Of the many tutorials that i've found, this one clicked. Thanks!!!

I genuinely had no clue how this worked cause a lot of methods were just so wordy, but this literally helped me so much???? thank u!!! 😭😭

Thank you, my man, you saved my life, well not really but you reminded me how to do it thank you very much, sir.

Thank you very much, the best video that i have found having been searching for a long a time

literally the only thing that helped every other explanation on yt was very long and complicated but this i can wrap my head around :)

THANK YOU VERY MUCH FOR THE EXPLANATION AND HARD WORK, YOU ARE AGENIUS👌👌👍👏

ive been struggling witn this for so log case everyone tells me different and complicated ways to do it but im glad i found this video cause it helped me SO MUCH

tysm!! its a week before my ppes and this helped so much ur a legend

I have a test tomorrow and literally had no clue how to do this but by the end of this I understand fully! Thanks for all your help! Subscribin

I've been through so many videos and ita only now it clicked you don't know the relief!! Tysmmm❤️

ive done all of the videos now, thanks alot , i have found a way i can revise that is easy and stress free , thanks for the hard work

THANKS BRO. IF THIS COMES UP IT IS A CONFIRMED 3 OR 4 MARKS FOR ME. KEEP UP THE EXCELLENT WORK !

Thank you so much for thiss! Have my mocks in a bit and was struggling to find a simple method for quadratic sequences with a clear explanation

I am in grade 7. I am going for the InIMC (India International Mathematics Competition) in 5 days. On the test deciding which 8 students are going, the first question had something about quadratic sequences. I didn't know what they were at the time, and got it wrong. I thought it was impossible, after watching this, I realise how UNBELIEVABLY EASY it was. Thank you so much for this amazing tutorial, you earned a subscriber. I genuinely love you for helping me so much. ❤❤❤

I have my gcse paper 3 tomorrow 😳

I’ve spent 3 years not understanding this, now I do. Big ups

This is by far the best explanation ever

Got some end of year mocks coming my way. This is of great help. Thanks!

omg what is this i'm gonna cry

If you guys have hegarty maths, quit the video on there and watch this guy instead. Maths Genie makes life soooo much easier.

Your the best teacher ever

Just realized you sound like my uncle, takes me back to when I was doing my GCSEs and A-level maths, got A*s in both so you helped me a hell of a lot

thank you so much, i have been struggling in this lesson for 1 week and you helped me

Thank you so much your channel helped me get into selection for set 1 maths ❤❤❤

THANKS SIR , YOU HELPED ME A LOT WITH MY NTH TERM NIGHTMARE!!! THANKS A LOT AGAIN BECAUSE IT COMES IN EVERY HIGHER EXAM

Cheers. Helped me out a lot

TYSM, I had an exam tommorow with NO CLUE how to solve this, saved my life! Ive gotten the hang of it now :)

This helped me so much because in my maths textbook they tell us to draw tables and put weird formulas

thanks mate helped alot after i forgot this other the summer

Sorry to bother you, but how on this question did you get 2n^2-4n+3. I don't really understand how you got 3. 5:53. Subscribed!

Thank you so much man my teacher goes over them so fast

Its 4am and i am looking for useful sh**t but your grateful content will save my ass after the exams ;)

wow I wish I've watched this tomorrow I missed this question on paper 2 hope I get it right on paper 4 after 2 days thanks a lot bro you helped a lot.

Thanks my guy textbook was awful needed this!

I have mocks next week and when I tell u this video came in clutch. Honestly tho thank you so much.

this has helped me with further maths but i wish i'd seen it earlier today before my maths paper 2 exam because i couldnt do this in today's test 😢

Thank you so so much this helped me A LOT I was trying to solve a question it took my like 15 min thinking and searching but nothing help as much as this,, applude 🙏🏿

THIS VIDEOS ACTUALLY HELPED ME

Choosing values so a = 1 makes this confusing, especially when you write n^2 instead of 1xn². In the next example, where b is -4, it's confusing that you skip over writing the constant -4 diff between all the terms. It's said quickly in speech, but not written down.

Thank you very much for this great explanation.

Thank u so much for posting this..it really helped me

YOU ARE A LIFE SAVER..

i have an maths test tomorrow i just learn i have it tomorrow as its my first day back since i had covid so i couldn’t cath up the topic the video really helped me to understand it in 5 mins thanks

Thank you so much! I will definitely pass my exam now!

U taught me this jn 2 minutes while my teacher didnt in a whole term, thanks bro

Wait how is the first example +1 and second one is -1 because they both seem the same

Tysm bro I needed this cos I forgot this shit from year 8 or 9

Omg thank you so much this is so helpful and really well explained. The best video I've found :)))👍🏼👍🏼

Dear sir can you solve this problem A quadratic sequence has the nth term n2-3 find the first two terms of this sequence

Realy appreciate the video thanks man.

THANK YOU I HAVENT ATTENDED A MATHS LESSON ALL TERM AND I HAVE A TEST TODAY

This is a really good explanation

U saved me thank u so much😊😊😊😊

Goat video wayy better than my teachee

Such a great video and purely logical unlike the other formula method. Can you do a me kind of video for cubic sequences? or someone reading the comments, share me a link if you know one... 😀

thank you man my paper is tomorrow from this one video my hope is that i can get good percentage and i had watched one video before watching this video and i cant understand it thank

Thanks, super helpful

why would it be ''+3'' if to get from -1 to -4 we have to minus 3? ( 5:38 )

Why do you take half of the second difference?

I have my exam in 5 hours. Inshallah I pass tmr.

thank you very much for this video😃

this really helped thank you!!
