The sum of three consecutive even numbers is 63, Find the last one ?
Choose the correct choice
A) 26  B) 24  C) 21  D) 23  E) 19
Let the first number be n   Let the second number be n + 2   Let the third number be n + 4   n + n + 2 + n + 4 = 63   Combine like terms:   3n + 6 = 63   3n = 63 - 6   3n = 57   n = 19   n + 2 = 21   n + 4 = 23   The last number is 23   Answer: 23
