The first five terms of the sequence are -8, -5/8, 0, 5/64 and 16/125
<h3>Recursive form of a sequence</h3>
Given the nth term of a sequence expressed as:
an= n^2-9/ n^3
Determine the first five terms
If n = 1
a1 = 1^2-9/ 1^3
a1 = -8/1
a1 = -8
If n = 2
a2 = 2^2-9/ 2^3
a2 = -5/8
If n = 3
a3= 3^2-9/ 1^3
a3 = 9-9/3^3
a3 = 0
If n = 4
a4 = 4^2-9/ 4^3
a4= 16-9/64
a4 = 5/64
If n = 5
a5 = 5^2-9/ 1^3
a5 = 25-9/5^3
a5 = 16/125
Hence the first five terms of the sequence are -8, -5/8, 0, 5/64 and 16/125

Answer:
Part A: See detail below.
Part B: Company B charges less than company A for 8 windows.
Part C: The saving using company B for 6 windows is $3.
Step-by-step explanation:
Part A:
Company A: (total charges) = ($6)x(N number of windows)+($12)
Company B: (total charges) = ($5)x(N number of windows)+($15)
Part B:
Company A for 8 windows: 6*8+12=$60
Company B for 8 windows: 5*8+15=$55
Part C:
(Saving) = (6*6+12)-(6*5+15)=48-45= $3
