Which recursively defined function has a first term equal to 15 and a common difference of 3?

The recursively defined function is:

Step-by-step explanation:

A recursively defined function has two parts:

In this case it is provided that:

The first term, f (1) = 15

Common difference, d = 3

Then the recursively defined function in this case is:
