Answer to Problem 32PPE
Recursive formula:
Explanation of Solution
Given sequence:
Calculation:
The first term of the sequence is
Since the each term of given sequence after the first term is obtained by adding the previous one by 15, therefore given sequence is an arithmetic sequence and common difference is
We know that the recursive formula for the arithmetic sequence with first term
By substituting the value of d, we get the recursive formula for the given sequence
