Find four consecutive odd numbers which add to 64.

Let the first number be x. The next three numbers are:
x + 2
x + 4
x + 6

Add them together to get 64:
x + (x + 2) + (x + 4) + (x + 6) = 64

Group like terms:
4x + 12 = 64

Using our equation calculator, we get:
x = 13

The next 3 odd numbers are:
x + 2 = 13 + 2 = 15
x + 4 = 13 + 4 = 17
x + 6 = 13 + 6 = 19

So the 4 consecutive odd numbers which add to 64 are:
(13, 15, 17, 19)
