Question

A sequence has its first term equal to 8 and each term of the sequence is obtained by adding 6 to the previous term. If f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence?

f(1) = 6 and f(n) = f(n - 1) + 8; n > 1

f(1) = 8 and f(n) = f(n - 1) + 6; n > 1

f(1) = 8 and f(n) = f(n - 1) + 6n; n > 1

f(1) = 6 and f(n) = f(n - 1) + 8n; n > 1

Answer 1

f(n-1) represents the previous term
Then add 8 to the previous term, so f(n-1) + 8= f(n)

Answer 2

Wait sorry!
I mean to say f(n-1)+6-f(n)! And f(1) = 8

Answer 3

f(n-1) + 6 = f(n)

Answer 4

B

Answer 5

Correct!
