http://www2.hawaii.edu/~janst/141/lecture/07-Proofs.pdf WebProve: If 3n+2 is odd, then n is odd. Proof: Assume 3n+2 is odd and n is even. Since n is even, then n=2k for some integer k. It follows that 3n+2 = 6k+2 = 2(3k+1). Thus, 3n+2 is … WebAnswer (1 of 6): If n is odd, then by definition n = 2k + 1 for some integer k. Therefore, 3n + 5 = 3(2k + 1) + 5 = 6k + 3 + 5 = 6k + 8 = 2(3k + 4) = 2m Where m = 3k + 4 If m is an … netwealth roll over request form
