Halfway Between 100 and 875

When you ask "What number is halfway between 100 and 875?" 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=875.

Halfway Between Line

To find the number halfway between 100 and 875, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 875 into our formula, we get:

(100 + 875)/2 = 487.5

Thus, the number halfway between 100 and 875 is 487.5.

To check that our answer is correct, we subtract 100 from 487.5 and subtract 487.5 from 875 and compare the two numbers:

487.5 - 100 = 387.5
875 - 487.5 = 387.5

As you can see, the halfway number is 387.5 higher than 100 and 387.5 lower than 875. Therefore, our halfway between answer of 487.5 above is correct.
