Jus expand them 1. A^2 -2ab +b^2
Then a^2+b^2
3 a^2+2ab+b^2
Common dif is 2ab
2(a^2+b^2)= 1 and 3 terms expansion...so thy r in ap
Then a^2+b^2
3 a^2+2ab+b^2
Common dif is 2ab

hello
a-b whole square =a2 + b2 -2ab
when 2ab is added to a2 + b2 -2abwe get-a2+ b2
and when we add 2ab to a2+b2 we get -a2+b2+2ab=(a+b)2
so (a-b)2,a2+b2,(a+b)2 are in ap with common difference +2ab
