The sum of the squares of three consecutive odd numbers is 2531.Find the numbers.



Options:
A .  26, 29 and 30
B .  26, 28 and 39
C .  27, 29 and 31
D .  31, 27 and 21
Answer: Option C

Let the numbers be x, x + 2 and x + 4.
Then, X2 +(x+2)2 +(x+4)2 = 2531=↔3x2 + 12x-2511 = 0
↔ X2+4x-837 = 0↔(x-27)(x+31) = 0↔x = 27.
Hence, the required numbers are 27, 29 and 31.
