For any integer n 0, it follows that 9 j(43n + 8). Solution: Proof. We prove this using induction. (1) If n = 0, then the statement is 9 j(43(0) + 8), or 9 j9, which is true. (2) Let k 0. Assume that 9 j(43 k+ 8). We need to show that 9 j(43( +1) + 8). Since 9 j(43k 31), there is an integer x such that 43k + 8 = 9x, so 4 k = 9x 8. 2 Homework ...

WebUse induction to show that 21 divides 4n+1 + 52n−1 whenever n is a positive integer. Solution Base case: n = 1. Clearly, 21 divides 42 + 51 = 21. Induction step: 4n+1 + 52 (n+1)−1 = 4 ∗ 4n + 25 ∗ 52n−1 = 4 ∗ (4n + 52n−1) + 21 ∗ 52n−1. Clearly 21 divides 21 ∗ 52n−1 by the induction hypothesis, 21 divides 4 ∗ (4n + 52n−1) Solution Base case : n … matt eagle mcghee insuranceWeb5 nov. 2024 · Given: 7^ (n+2)+8^ (2n+1) is divisible by 57. To find: Proof by mathematical induction Solution: Let P (n) = 7^ (n+2) + 8^ (2n+1). By mathematical induction, first we need prove that P (n) is divisible by 57 for n = 0. So P (0) = 7⁽⁰⁺²⁾+ 8⁽²ˣ⁰⁺¹⁾ = 7² + 8¹ = 49 + 8 = 57. 57 is divisble by 57, so P (0) is divisble by 57.
