WebMath 347 Worksheet: Induction Proofs, IV A.J. Hildebrand Example 2 Claim: All real numbers are equal. Proof: To prove the claim, we will prove by induction that, for all n 2N, the following statement holds: (P(n)) For any real numbers a 1;a 2;:::;a n, we have a 1 = a 2 = = a n. Base step: When n = 1, the statement is trivially true, so P(1) holds. WebExample 1. Show that the sum of the first n natural numbers can be determined using the formula, n ( n + 1) 2. Solution. Our goal is to show that 1 + 2 + 3 + … + n = n ( n + 1) 2 and we can use mathematical induction to prove this. We can begin by checking if the formula is true for k = 1.
