Which recursive formula can be used to generate the sequence shown, where f(1) = 5 and n > 1? 5,–1, –7, –13, –19

, where and

Step-by-step explanation:

The terms of the sequence are:

The first term of this sequence is .

There is a constant difference among the terms.

This constant difference can determined by subtracting a previous term from a subsequent term.

The general term of this arithmetic sequence is given  recursively by

We substitute the necessary values to obtain:

Or
