Halfway Between 85 and 721

When you ask "What number is halfway between 85 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=85 and Y=721.

Halfway Between Line

To find the number halfway between 85 and 721, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 721 into our formula, we get:

(85 + 721)/2 = 403

Thus, the number halfway between 85 and 721 is 403.

To check that our answer is correct, we subtract 85 from 403 and subtract 403 from 721 and compare the two numbers:

403 - 85 = 318
721 - 403 = 318

As you can see, the halfway number is 318 higher than 85 and 318 lower than 721. Therefore, our halfway between answer of 403 above is correct.
