Halfway Between 100 and 864

When you ask "What number is halfway between 100 and 864?" 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=864.

Halfway Between Line

To find the number halfway between 100 and 864, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 864 into our formula, we get:

(100 + 864)/2 = 482

Thus, the number halfway between 100 and 864 is 482.

To check that our answer is correct, we subtract 100 from 482 and subtract 482 from 864 and compare the two numbers:

482 - 100 = 382
864 - 482 = 382

As you can see, the halfway number is 382 higher than 100 and 382 lower than 864. Therefore, our halfway between answer of 482 above is correct.
