Suppose that Co C Cg... is a sequence defined as follows: o = 2, c, = 2, c, = 6, C = 30,- for every integer k 2 3. Prove that c, is even for each integer n2 0. Proof (by strong mathematical induction): Let the property P(n) be the following sentence. is even. We will show that P(n) is true for every integer n 2 0. Show that P(0), P(1), and P(2) are true: P(0), P(1), and P(2) are the statements "co is even," "c, is even," and "c, is even," respectively. These statements are true because -Select-- even. Show that for every integer k 2 2, if P(i) is true for each integer i from 0 through k, then P(k + 1) is true: Let k be any integer with k 2 2, and suppose c is --Select--- v for every integer i with 0s isk. This is the --Select- We must show that +1 is --Select--- . By definition of Co C. C2.. Ck +1 Since k z 2, we have that 0 sk-2s k. So we can apply the inductive hypothesis to conclude that c1 is 3 times an -Select---v Thus Ck +1 -Select-- is
