Halfway Between 87 and 721

When you ask "What number is halfway between 87 and 721?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=87 and Y=721.

Halfway Between Line

To find the number halfway between 87 and 721, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 87 and 721 into our formula, we get:

(87 + 721)/2 = 404

Thus, the number halfway between 87 and 721 is 404.

To check that our answer is correct, we subtract 87 from 404 and subtract 404 from 721 and compare the two numbers:

404 - 87 = 317
721 - 404 = 317

As you can see, the halfway number is 317 higher than 87 and 317 lower than 721. Therefore, our halfway between answer of 404 above is correct.
