Use the initial term and the recursive formula to find an explicit formula for the sequence an. Write your answer in simplest form.

Step-by-step explanation:

Given

Required

The explicit formula

First, calculate

Set n=2; So:

Substitute -25 for

Calculate the common difference (d)

So, the nth term is:

Open bracket

Collect like terms
