Prove using Mathematical Induction Show all of your work. Do not leave any steps out. Be sure to do the base case. 5. 1?2 + 2?3 + 3?4 + ... + N(N+1) = N(N+1)(N+2)/3, for N ? 1 6. 1(1!) + 2(2!) + 3(3!) + ... + N(N!) = (N+1)! - 1, for N ? 1 7. 1³ + 2³ + 3³ + ... + N³ = [N(N+1)/2]², for N ? 1 8. 11? – 6 is divisible by 5, for N ? 1 9. Prove using Mathematical Induction that postage of five cents or more can be achieved by using only 2-cent and 5-cent stamps. 10. Prove or disprove using Mathematical Induction that 2 + 4 + 6 + ... + 2N = (N+2)(N-1), for N ? 3
