The recursive formula would be:

This is because the first term, a₁, is 10. A recursive rule is dependent upon the term before it (a(n-1)) and the common ratio. The common ratio, or the number that each term is multiplied by, is -8.
Note that a square has 4 congruent and equal length sides.
The total perimeter is 36
Divide 36 with 4
36/4 = 9
9 inches is your answer
hope this helps
Just subsitute 8 for n
1/2(8)^2-1/2(8)
1/2(64)-4
32-4
