Divide 45 by 3 = 15. So you need a number below 15 e.g. 13, and a number above 15 e.g. 17. 13, 15, 17. Add them together = 45.

n-2+ n + n +2 = 45 3n = 45 n = 15 n = 13 n+2 = 17 n + 4 = 17

divide by 3 to get the middle one: 15 so the numbers are 13, 15, 17

Let x be the lowest number of the three. x + x + 2 + x + 4 = 45 3x + 6 = 45 3x = 39 x = 13 x + 2 = 15 x + 4 = 17
