For this question, we know that the first number is x, and the second number is x+1. Thus x+x+1(sum of the numbers)=29. 2x+1=29. If you do the calculations, you will find out that one number is 14, and the other number is 15.
To check, you add the numbers together and get 29, their difference is 1.
Thus, it is the correct answer.
