Use the principle of mathematical induction to show that the statement is true for all natural numbers. Sn : 13 + 2 + 3' + ... + n n' (n + 1) 2 What is the first step in the induction proof? O A. Show that the statement is true for n = 1. O B. Show that the statement is true for n = k + 1. O C. Show that the statement is true for n = k. O D. Show that the statement is true for n = 0. Evaluate both sides of the statement for S, . Sy: 13 = (1) ((1) + 1)2 4 Sy : 1 = 1 (Simplify your answers.) Is S, true? O Yes O No What is the next step in the induction proof? O A. Determine whether the statement holds for any number k + 1. O B. Assume the statement holds for some k, and determine whether it then holds for k + 1. O C. Determine whether the statement holds for some k. O D. Assume that the statement holds for k = 1, and determine whether it holds for k = 2. Carry out the next step in the proof.Use the principle of mathematical induction to show that the statement is true for all natural numbers.

The statement is true for S, but does not hold for Sk + 1, given that it holds for k. We have disproved S, by the principle of mathematical induction. O B. The statement is true for S and Sk+ 1, given that it holds for k.
