Halfway Between 21 and 683

When you ask "What number is halfway between 21 and 683?" 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=683.

Halfway Between Line

To find the number halfway between 21 and 683, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 683 into our formula, we get:

(21 + 683)/2 = 352

Thus, the number halfway between 21 and 683 is 352.

To check that our answer is correct, we subtract 21 from 352 and subtract 352 from 683 and compare the two numbers:

352 - 21 = 331
683 - 352 = 331

As you can see, the halfway number is 331 higher than 21 and 331 lower than 683. Therefore, our halfway between answer of 352 above is correct.
