Write a recursive formula and an explicit formula for the following arithmetic sequence.

10,17,24,31,38, ...

Recursive Formula: f (1) = 10, f (n) = f (n - 1) + 7 for n ≥ 2.

Explicit Formula: f (n) = 10+7 (n-)

Step-by-step explanation:

Recursive Formula: f (1) = first term, f (n) = f (n - 1) + d for n ≥ 2.

Explicit Formula: f (n) = f (1) + d (n-1)
