Halfway Between 100 and 724

When you ask "What number is halfway between 100 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=100 and Y=724.

Halfway Between Line

To find the number halfway between 100 and 724, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 724 into our formula, we get:

(100 + 724)/2 = 412

Thus, the number halfway between 100 and 724 is 412.

To check that our answer is correct, we subtract 100 from 412 and subtract 412 from 724 and compare the two numbers:

412 - 100 = 312
724 - 412 = 312

As you can see, the halfway number is 312 higher than 100 and 312 lower than 724. Therefore, our halfway between answer of 412 above is correct.
