Halfway Between 21 and 573

When you ask "What number is halfway between 21 and 573?" 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=573.

Halfway Between Line

To find the number halfway between 21 and 573, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 573 into our formula, we get:

(21 + 573)/2 = 297

Thus, the number halfway between 21 and 573 is 297.

To check that our answer is correct, we subtract 21 from 297 and subtract 297 from 573 and compare the two numbers:

297 - 21 = 276
573 - 297 = 276

As you can see, the halfway number is 276 higher than 21 and 276 lower than 573. Therefore, our halfway between answer of 297 above is correct.
