If the three numbers are consecutive then call the first number x. The number after x will be (x + 1) and the number after that will be (x + 2). To find the sum then add the three numbers up.

Add like terms
Subtract 3 from each side of the equation

Divide each side of the equation by 3

x = 41

So the three numbers are 41, 42 and 43. Check that they add to 126.
