Let the two numbers be x and y. We have the following equations: x + y = 21 and x - y = 15. Solving these equations simultaneously, we can add the two equations to get 2x = 36, which gives us x = 18. Substituting x = 18 back into the first equation, we find y = 3. Therefore, the two numbers are 18 and 3.
