Halfway Between 21 and 748

When you ask "What number is halfway between 21 and 748?" 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=748.

Halfway Between Line

To find the number halfway between 21 and 748, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 748 into our formula, we get:

(21 + 748)/2 = 384.5

Thus, the number halfway between 21 and 748 is 384.5.

To check that our answer is correct, we subtract 21 from 384.5 and subtract 384.5 from 748 and compare the two numbers:

384.5 - 21 = 363.5
748 - 384.5 = 363.5

As you can see, the halfway number is 363.5 higher than 21 and 363.5 lower than 748. Therefore, our halfway between answer of 384.5 above is correct.
