The idea is based on below two facts. 1) Sum of any two consecutive numbers is odd as one of them has to be even and the other odd. 2) 2 n = 2 n-1 + 2 n-1. If we take a closer look at 1) and 2), we can get the intuition behind the fact. Webis true, and so on. Consequently the property is true for all positive integers. Remark: In the basis step we may replace 1 with some other integer m. Then the conclusion is that the property is true for every integer n greater than or equal to m. Example: Prove that the sum of the n first odd positive integers is n2, i.e., 1+3+5+···+(2n− ...
