Halfway Between 100 and 868

When you ask "What number is halfway between 100 and 868?" 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=868.

Halfway Between Line

To find the number halfway between 100 and 868, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 868 into our formula, we get:

(100 + 868)/2 = 484

Thus, the number halfway between 100 and 868 is 484.

To check that our answer is correct, we subtract 100 from 484 and subtract 484 from 868 and compare the two numbers:

484 - 100 = 384
868 - 484 = 384

As you can see, the halfway number is 384 higher than 100 and 384 lower than 868. Therefore, our halfway between answer of 484 above is correct.
