Halfway Between 21 and 623

When you ask "What number is halfway between 21 and 623?" 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=623.

Halfway Between Line

To find the number halfway between 21 and 623, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 623 into our formula, we get:

(21 + 623)/2 = 322

Thus, the number halfway between 21 and 623 is 322.

To check that our answer is correct, we subtract 21 from 322 and subtract 322 from 623 and compare the two numbers:

322 - 21 = 301
623 - 322 = 301

As you can see, the halfway number is 301 higher than 21 and 301 lower than 623. Therefore, our halfway between answer of 322 above is correct.
