The numbers are 18 and 12
To find the midway point between 2 numbers, first you find the difference between them. Subtract the large from the small, in this case 42-18=24. So there is a difference of 24 between18 and 42. We need to find what halfway is, so we divide the difference by 2. In this case 24/2=12. So we know that 12 is half the difference between the numbers, so if we go that many up from the low number we will be half way. Add 12 to 18 and we get 30. This process works for finding the midpoint of any two numbers. Couldn't you just say 18 + 42 = 60 60/2= 30
