Answer: $11.80 for another 4 panes of glass.
Step-by-step explanation: We know that 9 panes of glass cost $26.55, but we should first find how many dollars would it cost per pane of glass, or 1.
So, we can divide 26.55 by 9 to find the price per 1 pan of glass.
26.55/9 = 2.95, or $2.95 per pane of glass.
Now, we want to know how much it will cost for 4 panes of glass. Simply multiply 2.95 by 4.
2.95 x 4 = 11.8, or $11.80 for another 4 panes of glass.

Answer:
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:
