If the sum of 9 consecutive integers is x, which of the must be true?
I. x is even
II. x is odd
III. x is a multiple of 2  Select the correct option.
A) I only  B) II only  C) III only  D) I and III  E) II and III
sum of 3 consecutive integers   = (n) + (n+1) + (n+2) ++ (n+3) + (n+4) + (n+5)+(n+6)+(n+7)+(n+8)   =9n+36   = odd + even =odd   = 2(5n+18) = divisible by 2   Hence, x is odd and divisible by 2.   Answer: II and III
