Yes, the concepts of odd and even apply to negative integers: any integer n n is even if and only if there is an integer k k such that n = 2k n = 2 k. The integer k k can be positive, negative, or zero. Thus, −6 = 2(−3) − 6 = 2 ( − 3) is even, as is 0 = 2 ⋅ 0 0 = 2 ⋅ 0. An integer is odd if and only if it is not even, so −7 − 7 ...Save.
