The difference of the squares of two consecutive odd integers is divisible by which of the following integers?

Question

Accepted Answer

Let the two consecutive odd integers be (2 n + 1) and (2 n + 3). Then, (2n + 3)2 - (2n + 1)2 = (2n + 3 + 2n + 1) (2n + 3 - 2n - 1) = (4n + 4) x 2 = 8(n + 1), which is divisible by 8.
