Don't type in ALL CAPS. It is the text communications equivalent of shouting and is both annoying and rude.

Pick the largest and the smallest number: 32 and 15. 32 + 15 = 47. You don't have a 3 to choose from, so the 32 is not one of your choices.

try 15 + 17. That is 32. 50 minus 32 is 18. You don't have an 18 in the list, so we know the 15 doesn't go with the 17.

try 15 + 16. That is 31. 50 minus 31 is 19. There is a 19 in the list. There you go. 15 + 16 + 19 = 50.
