Question

The sum of 3 33 consecutive odd numbers is 51 5151. What is the second number in this sequence?

Answer 1

15, 17, 19

Explanation:

Let the numbers be x, x + 2 x + 4

Sum = 51

x + x + 2 + x + 4 = 51

3x + 6 = 51

3x = 51 - 6

3x = 45

x = 45/3

x = 15

So first odd number = 15

Second odd number = x + 2 = 17

Third odd number = x + 4 = 19
