NettetAn example of the application of mathematical induction in the simplest case is the proof that the sum of the first n odd positive integers is n2 —that is, that (1.) 1 + 3 + 5 +⋯+ (2 n − 1) = n2 for every positive integer n. Let F be the class of integers for which equation (1.) holds; then the integer 1 belongs to F, since 1 = 1 2. Nettetfor all positive integers. Now let’s see how this works in practice, by proving Proposition 1. Proposition 1. The sum of the first n positive integers is 1 2 n(n+1). Initial step: If n =1,the sum is simply 1. Now, for n =1,1 2 n(n+1)=1 2 ×1×2=1.Sothe result is true for n =1. Inductive step: Stage 1: Our assumption (the inductive hypothesis ...
