WebExpert Answer. A proof of the following result is given. Result Let n Element of Z. If n^4 is even, then 3n + 1 is odd. Proof Assume that n^4 = (n^2)^2 is even. Since n^4 is even, n^2 is even. Furthermore, since n^2 is even, n is even. Because n is even, n = 2k for some integer k. Then 3n + 1 = 3 (2k) + 1 = 6k + 1 = 2 (3k) + 1.

Web7 jul. 2024 · Starting with any positive integer N, we define the Collatz sequence corresponding to N as the numbers formed by the following operations: N → N/2 ( if N is even) N → 3N + 1 (if N is odd) i.e. If N is even, divide it by 2 to get N/2. If N is odd, multiply it by 3 and add 1 to obtain 3N + 1. couch cushion cover miskelly
