Webn n is not even, then. n 2. n^2 n2 is not even. But there is a better way of saying “not even”. If you think about it, the opposite of an even number is odd number. Rewrite the contrapositive as. If n n is odd, then n^2 n2 is odd. Since n n is odd (hypothesis), we can let n = 2k + 1 n = 2k + 1 for some integer k k. Web6.
