When you ask "What number is halfway between 72 and 139?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=72 and Y=139.
To find the number halfway between 72 and 139, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 72 and 139 into our formula, we get:
(72 + 139)/2 = 105.5
Thus, the number halfway between 72 and 139 is 105.5.
To check that our answer is correct, we subtract 72 from 105.5 and subtract 105.5 from 139 and compare the two numbers:
105.5 - 72 = 33.5
139 - 105.5 = 33.5
As you can see, the halfway number is 33.5 higher than 72 and 33.5 lower than 139. Therefore, our halfway between answer of 105.5 above is correct.
