Halfway Between 72 and 724

When you ask "What number is halfway between 72 and 724?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=72 and Y=724.

Halfway Between Line

To find the number halfway between 72 and 724, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 72 and 724 into our formula, we get:

(72 + 724)/2 = 398

Thus, the number halfway between 72 and 724 is 398.

To check that our answer is correct, we subtract 72 from 398 and subtract 398 from 724 and compare the two numbers:

398 - 72 = 326
724 - 398 = 326

As you can see, the halfway number is 326 higher than 72 and 326 lower than 724. Therefore, our halfway between answer of 398 above is correct.
