Halfway Between 15 and 24

When you ask "What number is halfway between 15 and 24?" 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=24.

Halfway Between Line

To find the number halfway between 15 and 24, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 24 into our formula, we get:

(15 + 24)/2 = 19.5

Thus, the number halfway between 15 and 24 is 19.5.

To check that our answer is correct, we subtract 15 from 19.5 and subtract 19.5 from 24 and compare the two numbers:

19.5 - 15 = 4.5
24 - 19.5 = 4.5

As you can see, the halfway number is 4.5 higher than 15 and 4.5 lower than 24. Therefore, our halfway between answer of 19.5 above is correct.
