Halfway Between 21 and 563

When you ask "What number is halfway between 21 and 563?" 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=563.

Halfway Between Line

To find the number halfway between 21 and 563, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 563 into our formula, we get:

(21 + 563)/2 = 292

Thus, the number halfway between 21 and 563 is 292.

To check that our answer is correct, we subtract 21 from 292 and subtract 292 from 563 and compare the two numbers:

292 - 21 = 271
563 - 292 = 271

As you can see, the halfway number is 271 higher than 21 and 271 lower than 563. Therefore, our halfway between answer of 292 above is correct.
