Question

The sum of three consecutive even integer numbers is 2556. The middle among the three is?

A

852.

B

853.

C

851.

D

854.

Soln.
Ans: a

Let the numbers be 2n - 2, 2n and 2n + 2. The sum is 6n = 3 x 2n = 3 x middle. We are given 3 x middle = 2556, ⇒ middle = $2556/3$, i.e., middle = 852.
