Halfway Between 100 and 728

When you ask "What number is halfway between 100 and 728?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=100 and Y=728.

Halfway Between Line

To find the number halfway between 100 and 728, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 728 into our formula, we get:

(100 + 728)/2 = 414

Thus, the number halfway between 100 and 728 is 414.

To check that our answer is correct, we subtract 100 from 414 and subtract 414 from 728 and compare the two numbers:

414 - 100 = 314
728 - 414 = 314

As you can see, the halfway number is 314 higher than 100 and 314 lower than 728. Therefore, our halfway between answer of 414 above is correct.
