Question

What is the recursive formula for this arithmetic sequence?
-4,3,10,17,...

Answer 1

D

Explanation:

Answer 2

Explanation:

Notice how each new term of this sequence is 7 greater than the previous term.

Thus, the common difference is 7. The first term is -4.

A formula for the nth term is a(n) = -4 + 7(n-1).

A recursive formula would be a(n+1) = a(n) + 7
