Halfway Between 100 and 634

When you ask "What number is halfway between 100 and 634?" 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=634.

Halfway Between Line

To find the number halfway between 100 and 634, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 634 into our formula, we get:

(100 + 634)/2 = 367

Thus, the number halfway between 100 and 634 is 367.

To check that our answer is correct, we subtract 100 from 367 and subtract 367 from 634 and compare the two numbers:

367 - 100 = 267
634 - 367 = 267

As you can see, the halfway number is 267 higher than 100 and 267 lower than 634. Therefore, our halfway between answer of 367 above is correct.
