To write the recursive formula for the arithmetic sequence where the first three terms are −19,−13,−7, follow these steps:

Identify the common difference: Calculate the differences between consecutive terms:

−13−(−19)=6

−7−(−13)=6

 The common difference d is 6.

Write the recursive formula:

The general form of the recursive formula for an arithmetic sequence is:

= + d

In this case, the common difference d is 6. The first term
