Halfway Between 100 and 720

When you ask "What number is halfway between 100 and 720?" 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=720.

Halfway Between Line

To find the number halfway between 100 and 720, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 720 into our formula, we get:

(100 + 720)/2 = 410

Thus, the number halfway between 100 and 720 is 410.

To check that our answer is correct, we subtract 100 from 410 and subtract 410 from 720 and compare the two numbers:

410 - 100 = 310
720 - 410 = 310

As you can see, the halfway number is 310 higher than 100 and 310 lower than 720. Therefore, our halfway between answer of 410 above is correct.
