Halfway Between 15 and 63

When you ask "What number is halfway between 15 and 63?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=15 and Y=63.

Halfway Between Line

To find the number halfway between 15 and 63, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 63 into our formula, we get:

(15 + 63)/2 = 39

Thus, the number halfway between 15 and 63 is 39.

To check that our answer is correct, we subtract 15 from 39 and subtract 39 from 63 and compare the two numbers:

39 - 15 = 24
63 - 39 = 24

As you can see, the halfway number is 24 higher than 15 and 24 lower than 63. Therefore, our halfway between answer of 39 above is correct.
