Halfway Between 1 and 255

When you ask "What number is halfway between 1 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=1 and Y=255.

Halfway Between Line

To find the number halfway between 1 and 255, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 255 into our formula, we get:

(1 + 255)/2 = 128

Thus, the number halfway between 1 and 255 is 128.

To check that our answer is correct, we subtract 1 from 128 and subtract 128 from 255 and compare the two numbers:

128 - 1 = 127
255 - 128 = 127

As you can see, the halfway number is 127 higher than 1 and 127 lower than 255. Therefore, our halfway between answer of 128 above is correct.
