Halfway Between 21 and 23

When you ask "What number is halfway between 21 and 23?" 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=23.

Halfway Between Line

To find the number halfway between 21 and 23, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 23 into our formula, we get:

(21 + 23)/2 = 22

Thus, the number halfway between 21 and 23 is 22.

To check that our answer is correct, we subtract 21 from 22 and subtract 22 from 23 and compare the two numbers:

22 - 21 = 1
23 - 22 = 1

As you can see, the halfway number is 1 higher than 21 and 1 lower than 23. Therefore, our halfway between answer of 22 above is correct.
