To write the recursive formula for the sequence 5,10,15,20,… (where n>1), follow these steps:

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

10−5=5

15−10=5

20−15=5 The common difference d is 5.

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 5. The first term
