Answer:
32 hours.
Step-by-step explanation:
Let x represent the time taken by Russell and Aaron to build the shed.
We have been given that Russell and Aaron can build a shed in 8 hours when working together. Aaron works three times as fast as Russel.
Russell's work rate would be .
Since Aaron works three times as fast as Russel, so Aaron's work rate would be .
Part of work done by in one hour would be .
We can represent our given information in an equation as:
Let us solve for x.
Therefore, it will take Russell 32 hours to build the shed working alone.

for
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:
