WebProof: Let P (n) denote the property 1 + 2 + … + n = n (n+1)/2. We show that P (n) holds for all natural numbers by induction on the natural number n. Base step (n=0): The left-hand side of P (0) is the "empty sum" where we add nothing. Hence it equals 0. The right-hand side is 0 (0+1)/2 = 0. Since both sides are equal, P (0) is true. WebProof. We will prove this by induction. Base Case: Let n = 1. Then the left side is 1 2 = 2 and the right side is 1 2 3 3 = 2. Inductive Step: Let N > 1. Assume that the theorem holds for n < N.
