Halfway Between 21 and 25

When you ask "What number is halfway between 21 and 25?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=21 and Y=25.

Halfway Between Line

To find the number halfway between 21 and 25, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 25 into our formula, we get:

(21 + 25)/2 = 23

Thus, the number halfway between 21 and 25 is 23.

To check that our answer is correct, we subtract 21 from 23 and subtract 23 from 25 and compare the two numbers:

23 - 21 = 2
25 - 23 = 2

As you can see, the halfway number is 2 higher than 21 and 2 lower than 25. Therefore, our halfway between answer of 23 above is correct.
