Question


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

Options:
A .  3
B .  4
C .  6
D .  7
Answer: Option B

Let the two consecutive even integers be 2n and (2n + 2). Then,


(2n + 2)2 = (2n + 2 + 2n)(2n + 2 - 2n)


     = 2(4n + 2)


     = 4(2n + 1), which is divisible by 4.
