55:26 the 128 three digit no are divisible by 7

15:19 first term is 1/3 and common difference is 4/3

Thank You Sir! I was facing some problems in understanding how to solve questions in this chapter but now I'm not. Thank You Again.👍👍👍

37:30 sir - (it's not be "165"it will be "164" And sorry if I was wrong. Or any typing mistake. Your faithfull Student.😊😊

👍 32:08. n = 34 55:37, n = 128

37:37 sir 161+3 = 164 not 165 if it is 165 then it will divided by 3

15:12 a=1/3 ; d=4/3❤❤❤❤

15:16 FIRST TERM - 1/3 COMMON DIFFERENCE - 4/3

A.P= COMMON DIFFERENCE ARE EQUAL A NO⁰A SEQUENCE IS CALLED A.P 15:31

35:04 sir ne galat add kiya. 161 + 3 = 164. Not 165 and 165 is divisible by 3 😊❤

1:08:03 , -180.

37:20 sir the 3 will be getting divided by 165 the answer will be 55

35:06 a minor mistake 161+3=164 not 165. very nice explanation🥰🥰

15:18 a=1/3 , d= 4/3

15:20 a = 1/3 , d = 4

56:10 60

15:31 The common difference is the same i,e the term is an A.P

21:39 d1= √2 and d2=√2 since it is an AP . Next term is √50,√72,√98

1:12:41 answer is 1046.5

15:15 a= 1/3 d= 4/3

15:15 a = 1/3 d =4/3

common difference equal hoga toh AP hoga 15:30

Watching this gem in the night before boards🥹🫶🏻

कुछ नशा तिरंगे की आन का है कुछ नशा मातृभूमि की शान का है हम लहराएंगे हर जगह ये तिरंगा नशा ये हिंदुस्तान की शान का है स्वतंत्रता दिवस की शुभकामनाएं 🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳

15:18 a=1/3, d=4/3

1:04:52

Very nice explanation sir 😀 thank you for this wonderful lecture

1:10:18 -180 is answer

SIR IAM GOOD STUDENT ANSWER IS (iii) a=1/3 i use formula a²-a¹=5/3 -1/3=4/0 15:11 ✅

56:16, The A.P is 4,10,16,22,28,34_ _ _ _ _.

28:33 -77

This is something amazing ❤️ first explaining the concepts and then Sunday ko dhamakedar questions 🎉

36:06 3

15:31 we can check that by verifying if the difference is same

37:35 it is divisible by 3

15:15 a=1/3 and d = 4/3

Thank you sir i m watching this lecture one day before my pre board ❤😂🙏

Best teacher for maths ever!!!!!!

55:34 ans= 128 three digit numbers are divisible by

15:21 the answer is the first term is 1/3 and the difference is 4/3

Sir A= 1/3 & D= 4

12:45 -1,-1/2,0,1/2

15:31 Using Common difference formula a2 -a1 = 2 & a3-a2 = 4 therefore it is not an A.P ❤❤❤❤❤❤❤❤

Thank you sir for clearing our doubts❤❤❤❤

21:33 it is A.P 5root 2 6 root 2 7 root 2

1:42:22 sir nth term kya aayegi? Btw this is very helpful 😊❤🎉

32:10 a = 7 , d = 6 and n = 34 terms

a=1/3 and d= 4/3 ans

15:04 a- 1/3 d-4/3

Answer) The three digits no are 128 is divisible by 7

15.13,first term = 1/2 d=4/3

Raat me padhne wale like karo😅😂😊

Watching before 1 day of pre board exam 😂 thankyou sir ❣️

You are RAJA 😂.......Great explanation.........👍

Thankyou so much sir, for this fantastic explanation....😇😇

55:34 128 three digit numbers

56:02 nth term is N= 60

15:19 ( a=1/3 ) ( d=4/3 )

15:15 a=1/3 d=4/3

EAST AND BEST SIR IS THE BEST❤❤ 0:40

15:12 Ans will be a = 1/3 and d = 4/3

35:20 sir 164/3 hoga

1:26:27😂😂😂😂😂😂

15:19 first term is 1/3 and common difference is 4/3

OK SIR I DO EX 5.1 I ACCEPT YOUR ADVICE ❤❤❤ 24:49

15:09 A is 1/3 D is 4/3

41:30 , it is 64. The 29th term of the A.P is 64.

55:31 nth term is N= 128

15:17 (iii) a=1/3 and d=4/3

a=1/3 d=4

15:17 a = 1/3 and d -= 4/3

Sir you r amazing teacher may Allah bless you 😌

15:13 is a= 1/3 and d=4/3

1:04:00 ❤❤

1:04:03 ❤❤❤❤❤❤❤❤❤❤❤❤

Every teacher is okay but Ashu sir is lobbb🫶🏻🫶🏻

15:19 a=1/3;d=4/3

13:00 -1,-1/2,0,1/2,1

1:07:43 -156

(iii) d=4/3 15:11

🎉🎉🎉🎉🎉 1:04:16

15:17 a=1/3 and d= 4/3.

43:44 n=5

15:17 a=1/3, d =4/3😊

1:40:21 Sn = -465.

15:14 A=1/3 D=4/3

35:12 n=164/3

55:31 there are 128 three - digit no. can be divided by 7...!

15:12 a1/3 d4/3

15:14 here a=1/3 and d= 4/3

55:32 n=142🎉

55:39, n=60.

4/3 15:13

1:01:24 148

A=1/3.....D=4/3 15:20

37:44 yaha per 164/3 hoga naki 165/3 nahi toh bah completely divide ho jaiga apne galti ki hai

15:06 ans is FIRST TERM == 1/3 DIFFERENCE== 4/3

15:09 a=1/3 d=4/3
