WebDeduction is drawing a conclusion from something known or assumed. This is the type of reasoning we use in almost every step in a mathematical argument. Mathematical induction is a particular type of mathematical argument. It is most often used to prove general statements about the positive integers. WebSolution: Step 1: If n isn’t a multiple of 3, it is either one or two more than a multiple of 3. Thus we can write n = 3k + 1 or n = 3k + 2, with k being any integer. Step 2: Now prove that the statement is true for each case. Case 1: Show that if n = 3k + 1, then n 2 - 1 is a multiple of 3. n²-1 = (3k + 1) ² -1.
