Halfway Between 100 and 725

When you ask "What number is halfway between 100 and 725?" 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=725.

Halfway Between Line

To find the number halfway between 100 and 725, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 725 into our formula, we get:

(100 + 725)/2 = 412.5

Thus, the number halfway between 100 and 725 is 412.5.

To check that our answer is correct, we subtract 100 from 412.5 and subtract 412.5 from 725 and compare the two numbers:

412.5 - 100 = 312.5
725 - 412.5 = 312.5

As you can see, the halfway number is 312.5 higher than 100 and 312.5 lower than 725. Therefore, our halfway between answer of 412.5 above is correct.
