WebYear 10 - June Mock 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 …

Web5 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. Now, for n = 1. Webshow this by using induction. When n = 0, we see that 52n+1 + 22n+1 = 7, and so it is divisible by 7. Suppose now that 7 divides 5 2n+1+ 2 for some nonnegative integer n. … bracken color definition https://traffic-sc.com

http://zimmer.fresnostate.edu/~doreendl/111.14f/hwsols/hw10sols.pdf WebThe first term in that sum is divisible by 8 per the assumption (it's the Kth domino, and we're assuming that it falls). But the second term is 8 multiplied by a whole number! It's also divisible by 8! And the neatest thing is that this whole sum is equal to 5 2K+1 + 7 - so we've proven that if 52K + 7 % 8 = 0, then 52 (K+1) + 7 % 8 = 0 .
