👉 Learn about sequences. A sequence is a list of numbers/values exhibiting a defined pattern. A number/value in a sequence is called a term of the sequence. There are many types of sequence, among which are: arithmetic and geometric sequence.
An arithmetic sequence is a sequence in which each term of the sequence is obtained by adding a pre-determined value, called the common difference, to the preceding term. A geometric sequence is a sequence in which each term of the sequence is obtained by multiplying a pre-determined value, called the common ratio, to the preceding term.

@peterlohnes1 3 года назад

A lot of students always get confused by the SUB numbers...the SUB numbers are NOT part of the equation. They are like saying term one, term two, term three....they dont go into ANY of the calculations. At all. Its like saying a Audi8, Audi7, Audi6...they mark a new generation or next years model, Audi 8 doesn't have 8 tires or anything, its just the next years model. But it takes so long to write down term one, term two, term three in words, so we write t1, t2, t3, or a1, a2, a3. The only relationship the sub numbers have is to say a3 comes after a2, and a2 comes after a1, just like models of a car.

So this would be for an arithmetic recursive formula, right? And if so do u have a geometric recursive formula example?

Hi! I’m sure you covered this in class, but I recursive formula for a geometric sequence could look something like this Un = Un-1(.5) UsubN = UsubN-1(.5)

Sir, I have a question, are all explicit formulas arithmetic? Because my teacher told us to make an explicit formula for this: 2, 4, 7, 11, 16, ... & I think it's supposed to be under recursive..

f(n+1)=-2f(n)+8 and f(1)= for n>1? Please help list the first five terms

@kelseysanders9251 4 года назад

Just trying to clarify wouldn't a4 = 10? Because k=3 and when you plug-in to the formula it would look like this: a1+1=1^2+1 --> a2=2 a2+1=2^2+1 --> a3=5 a3+1=3^2+1 --> a4=10 * a4+1=4^2+1 --> a5=17

@lol.7031 2 года назад

No it wouldn’t, because it uses the last value you gained, not the 3; so it’d be 5^2 + 1

@alyssa5236 4 года назад

Thank you, this was helpful!

@edberaga6357 4 года назад

I don't know how did the "a3+1 = 5^2 +1".... isn't the k is 3? shouldn't supposed "a3+1 = 3^2 +1"

@violetsylvia1951 5 лет назад

why is a of 1 =2. shoud it not equal 1?

@Hi-bs7xv 5 лет назад

No because a of 1 means that it is the first term in the sequence and 2 is what the 1st term in the sequence is does that make sense
