To write the recursive formula for the arithmetic sequence where the first three terms are 45,39,33, follow these steps:

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

39−45=−6

33−39=−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
