Let first number = x
Then second number will one more so that next number wil x+1
Given that sum of whose squares is 365.
x2+ ( x + 1)2 = 365
use formula of (a +b)2 = a2 + 2ab +b2
x2+ x2+ 2x + 1 – 365 = 0
2x2+ 2x – 364 = 0
Divide by 2 to simplify it
x2+ x – 182 = 0
factorize
13 and -14
so the answer is 13 and 14
