What is the greatest of 3 consecutive integers whose sum is 18 ?  Select the correct option:
A) 6  B) 7  C) 8  D) 9  E) 5

Rationale: "the sum of three consecutive integers can be written as n + ( n + 1 ) + ( n + 2 ) = 3 n + 3 if the sum is 24 , we need to solve the equation 3 n + 3 = 18 ; = > 3 n = 15 ; = > n = 5 the greatest of the three numbers is therefore 5 + 2 = 7 answer : b"
Answer: B
