Couldn't it be any three integers that add up to more than 42? Is there any other information in the problem?

x + x+1 + x+2 >= 42 3x + 3 >= 42 3x >= 45 x >= 15 Every integer sequence from 15 is correct.

Thats only part of it krish, the problem states no less not just equal to, the solution has to satisfy the complete conditions, william.briand also has a solution, but it too is not complete. Primarily because of an error on the third step which should read: 3x>=39 this of course solves to x=>13 this then would include both of your answers.
