the sum of 4 consecutive even numbers is 140 . what would be the largest number ?
Pick one.
A) 33
B) 38
C) 70
D) 123
E) 12

Rationale: let the four consecutive even numbers be 2 ( x - 2 ) , 2 ( x - 1 ) , 2 x , 2 ( x + 1 ) their sum = 8 x - 4 = 140 = > x = 18 smallest number is : 2 ( x + 1 ) = 38 . answer : b
Answer: B
