Halfway Between 100 and 708

When you ask "What number is halfway between 100 and 708?" 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=708.

Halfway Between Line

To find the number halfway between 100 and 708, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 708 into our formula, we get:

(100 + 708)/2 = 404

Thus, the number halfway between 100 and 708 is 404.

To check that our answer is correct, we subtract 100 from 404 and subtract 404 from 708 and compare the two numbers:

404 - 100 = 304
708 - 404 = 304

As you can see, the halfway number is 304 higher than 100 and 304 lower than 708. Therefore, our halfway between answer of 404 above is correct.
