Halfway Between 13 and 255

When you ask "What number is halfway between 13 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=13 and Y=255.

Halfway Between Line

To find the number halfway between 13 and 255, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 255 into our formula, we get:

(13 + 255)/2 = 134

Thus, the number halfway between 13 and 255 is 134.

To check that our answer is correct, we subtract 13 from 134 and subtract 134 from 255 and compare the two numbers:

134 - 13 = 121
255 - 134 = 121

As you can see, the halfway number is 121 higher than 13 and 121 lower than 255. Therefore, our halfway between answer of 134 above is correct.
