# Find the sum of the following arithmetic progressions:

(x-y)^{2}, (x^{2}+y^{2}), (x+y)^{2}, … to n terms

Answer :

for the **given** AP the first term a is (x - y)^{2} and common difference d is a difference of the second term and first term, which is

**To find**: the sum of given AP

**Formula:** for the sum of AP is given by
