When you ask "What number is halfway between 21 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=21 and Y=24.
To find the number halfway between 21 and 24, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 21 and 24 into our formula, we get:
(21 + 24)/2 = 22.5
Thus, the number halfway between 21 and 24 is 22.5.
To check that our answer is correct, we subtract 21 from 22.5 and subtract 22.5 from 24 and compare the two numbers:
22.5 - 21 = 1.5
24 - 22.5 = 1.5
As you can see, the halfway number is 1.5 higher than 21 and 1.5 lower than 24. Therefore, our halfway between answer of 22.5 above is correct.
