The sum of four consecutive even numbers is 36. Find the sum of the squares of these numbers?
Choose the correct option
A) 296 B) 252 C) 344 D) 388 E) none of these

Rationale: let the four numbers be x , x + 2 , x + 4 and x + 6 . = > x + x + 2 + x + 4 + x + 6 = 36 = > 4 x + 12 = 36 = > x = 6 the numbers are 6 , 8 , 10 and 12 . sum of their squares = 62 + 82 + 102 + 122 = 36 + 64 + 100 + 144 = 344 . answer : c
Answer: C
