Use the explicit formula to find a recursive formula for the sequence an. Write your answer in simplest form. The recursive formula should depend on an–1. an= – 9n–5 an=
The explicit formula for the sequence is an = -9n - 5.
To find a recursive formula, we need to express an in terms of an-1.
From the explicit formula, we can see that each term is obtained by subtracting 9 from the previous term. Therefore, we can write the recursive formula as:
an = an-1 - 9
This recursive formula expresses each term in the sequence as the previous term minus 9.
