Halfway Between 31 and 255

When you ask "What number is halfway between 31 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=31 and Y=255.

Halfway Between Line

To find the number halfway between 31 and 255, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 31 and 255 into our formula, we get:

(31 + 255)/2 = 143

Thus, the number halfway between 31 and 255 is 143.

To check that our answer is correct, we subtract 31 from 143 and subtract 143 from 255 and compare the two numbers:

143 - 31 = 112
255 - 143 = 112

As you can see, the halfway number is 112 higher than 31 and 112 lower than 255. Therefore, our halfway between answer of 143 above is correct.
