Step-by-step explanation:
Given
-- First Term
--- half common difference
Required
Find the recursive rule
First, we calculate the common difference
Multiply through by 2
The second term of the sequence is:
The third term is:
So, we have:
Substitute f(1) for 3
Express 1 as 2 - 1
Substitute n for 2
Similarly:
Substitute f(2) for 11
Express 2 as 3 - 1
Substitute n for 3
Hence, the recursive is:
