For the positive integers, the perfect squares(whole numbers whose square root yields a postive integer form a pattern, namely: 1^2 = 1, 2^2= 4, 3^2=9..., N^2 = (N-1)^2 + 2N-1. All non perfect square whole number can indeed be approximated between two successive perfect squares. Of course, you could try prime factorization of numbers that have two or more prime factor pairs.
