Answer 1

Answer 2

Hey mate.


Let, n=3


then, by the first formula

(n^2-1/2) = 9-1/2 = 8/2 = 4

now using another formula.

(n^2+1/2) = 9+1/2 = 10/2 = 5



Now we've got values


(3,4,5)


So, now check if this a Pythagorean Triplet.


Now, you can take another example by taking n=any odd no.


Hope it helps you.
