Answer:
The answer to your question is Area = 49n² - 70n + 25
Step-by-step explanation:
Data
Length of the side = 7n - 5
Formula
Area of a square = side x side
Process
1.- Substitute values
Area = (7n - 5)(7n - 5)
2.- Expand
Area = 49n² - 35n - 35n + 25
3.- Simplify
Area = 49n² - 70n + 25
4.- The polynomial is 49n² - 70n + 25
The common difference is x
the first term is x+1
a_8 = x+1 + x(8-1) = x+1 + 7x = 8x + 1
