Problem 2 from prior weeks.
Correct!
Explanation:
The product is always even. An even number is divisible by two by definition. The product of an even number with any other integer will also be divisible by two and hence even. Algebraically, an even number can be expressed as 2n, an odd number as 2m + 1. Their product would be 2n(2m+1) = 2(2mn+1) showing that two is a factor and therefore that the product is an even number.
