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?

Answer 1

choices?

Answer 2

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 3

Choice (2) is correct.

Since the first term is 8, so f(1) = 8, so you should have immediately eliminated choices A and D.
