Question

Someone please help me for a medal and fan?!?!

Answer 1

A sequence has its first term equal to 3, and each term of the sequence is obtained by adding 5 to the previous term. If f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence?

Answer 2

f(n) is term, so f(n-1) is previous term

Answer 3

So you can express it as \(f(n) = 5+f(n-1)\)

Answer 4

Does that make sense?

Answer 5

Yeah, it does. I got f(1) = 3 and f(n) = f(n - 1) + 5; n > 1, is that correct?

Answer 6

Looks good!

Answer 7

3+5(n-1)

Answer 8

Okay, thanks geerky!
