Halfway Between 11 and 255

When you ask "What number is halfway between 11 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=11 and Y=255.

Halfway Between Line

To find the number halfway between 11 and 255, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 255 into our formula, we get:

(11 + 255)/2 = 133

Thus, the number halfway between 11 and 255 is 133.

To check that our answer is correct, we subtract 11 from 133 and subtract 133 from 255 and compare the two numbers:

133 - 11 = 122
255 - 133 = 122

As you can see, the halfway number is 122 higher than 11 and 122 lower than 255. Therefore, our halfway between answer of 133 above is correct.
