Halfway Between 100 and 702

When you ask "What number is halfway between 100 and 702?" 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=702.

Halfway Between Line

To find the number halfway between 100 and 702, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 702 into our formula, we get:

(100 + 702)/2 = 401

Thus, the number halfway between 100 and 702 is 401.

To check that our answer is correct, we subtract 100 from 401 and subtract 401 from 702 and compare the two numbers:

401 - 100 = 301
702 - 401 = 301

As you can see, the halfway number is 301 higher than 100 and 301 lower than 702. Therefore, our halfway between answer of 401 above is correct.
