Halfway Between 100 and 327

When you ask "What number is halfway between 100 and 327?" 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=327.

Halfway Between Line

To find the number halfway between 100 and 327, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 327 into our formula, we get:

(100 + 327)/2 = 213.5

Thus, the number halfway between 100 and 327 is 213.5.

To check that our answer is correct, we subtract 100 from 213.5 and subtract 213.5 from 327 and compare the two numbers:

213.5 - 100 = 113.5
327 - 213.5 = 113.5

As you can see, the halfway number is 113.5 higher than 100 and 113.5 lower than 327. Therefore, our halfway between answer of 213.5 above is correct.
