Halfway Between 21 and 753

When you ask "What number is halfway between 21 and 753?" 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=753.

Halfway Between Line

To find the number halfway between 21 and 753, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 753 into our formula, we get:

(21 + 753)/2 = 387

Thus, the number halfway between 21 and 753 is 387.

To check that our answer is correct, we subtract 21 from 387 and subtract 387 from 753 and compare the two numbers:

387 - 21 = 366
753 - 387 = 366

As you can see, the halfway number is 366 higher than 21 and 366 lower than 753. Therefore, our halfway between answer of 387 above is correct.
