Halfway Between 21 and 603

When you ask "What number is halfway between 21 and 603?" 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=603.

Halfway Between Line

To find the number halfway between 21 and 603, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 603 into our formula, we get:

(21 + 603)/2 = 312

Thus, the number halfway between 21 and 603 is 312.

To check that our answer is correct, we subtract 21 from 312 and subtract 312 from 603 and compare the two numbers:

312 - 21 = 291
603 - 312 = 291

As you can see, the halfway number is 291 higher than 21 and 291 lower than 603. Therefore, our halfway between answer of 312 above is correct.
