the sum of 4 consecutive even numbers is 52 , find the third number ?
Choose the correct choice from the following.
A) 14 B) 10 C) 12 D) 16 E) 20

Rationale: 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 n + n + 2 + n + 4 + n + 6 = 52 combine like terms : 4 n + 12 = 52 4 n + 12 = 52 4 n = 52 - 12 4 n = 40 n = 10 n + 2 = 12 n + 4 = 14 n + 6 = 16 the third number is 14 answer : a
Answer: A
