Halfway Between 99 and 255

When you ask "What number is halfway between 99 and 255?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=99 and Y=255.

Halfway Between Line

To find the number halfway between 99 and 255, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 99 and 255 into our formula, we get:

(99 + 255)/2 = 177

Thus, the number halfway between 99 and 255 is 177.

To check that our answer is correct, we subtract 99 from 177 and subtract 177 from 255 and compare the two numbers:

177 - 99 = 78
255 - 177 = 78

As you can see, the halfway number is 78 higher than 99 and 78 lower than 255. Therefore, our halfway between answer of 177 above is correct.
