Please prove this statement using indirect method of discrete mathematics. If n = ab, where a and b are positive integers, then a ≤ √n or b ≤ √n
Prove: If n and a are positive integers and n=(a^2+ 1)/2, then n is the sum of the squares of two consecutive integers (that is, n=k^2+ (k+1)^2 for some integer k).
