Halfway Between 100 and 636

When you ask "What number is halfway between 100 and 636?" 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=636.

Halfway Between Line

To find the number halfway between 100 and 636, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 636 into our formula, we get:

(100 + 636)/2 = 368

Thus, the number halfway between 100 and 636 is 368.

To check that our answer is correct, we subtract 100 from 368 and subtract 368 from 636 and compare the two numbers:

368 - 100 = 268
636 - 368 = 268

As you can see, the halfway number is 268 higher than 100 and 268 lower than 636. Therefore, our halfway between answer of 368 above is correct.
