Halfway Between 21 and 653

When you ask "What number is halfway between 21 and 653?" 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=653.

Halfway Between Line

To find the number halfway between 21 and 653, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 653 into our formula, we get:

(21 + 653)/2 = 337

Thus, the number halfway between 21 and 653 is 337.

To check that our answer is correct, we subtract 21 from 337 and subtract 337 from 653 and compare the two numbers:

337 - 21 = 316
653 - 337 = 316

As you can see, the halfway number is 316 higher than 21 and 316 lower than 653. Therefore, our halfway between answer of 337 above is correct.
