Find the middle one when The sum of five consecutive even numbers is 65? Choose the most appropriate option.
A) 9 B) 13 C) 15 D) 17 E) 11
Let the first number be n   Let the second number be n + 2   Let the third number be n + 4   Let the third number be n + 6   Let the third number be n + 8   n + n + 2 + n + 4 + n + 6 + n + 8= 65   Combine like terms:   5n + 20 = 65   5n = 65 - 20   5n = 45   5n = 45   n = 9   n + 2 = 11   n + 4 = 13   n + 6 = 15   n + 8 = 17   The middle number is 13   Answer: 13
