Halfway Between 21 and 675

When you ask "What number is halfway between 21 and 675?" 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=675.

Halfway Between Line

To find the number halfway between 21 and 675, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 675 into our formula, we get:

(21 + 675)/2 = 348

Thus, the number halfway between 21 and 675 is 348.

To check that our answer is correct, we subtract 21 from 348 and subtract 348 from 675 and compare the two numbers:

348 - 21 = 327
675 - 348 = 327

As you can see, the halfway number is 327 higher than 21 and 327 lower than 675. Therefore, our halfway between answer of 348 above is correct.
