Halfway Between 17 and 255

When you ask "What number is halfway between 17 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=17 and Y=255.

Halfway Between Line

To find the number halfway between 17 and 255, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 255 into our formula, we get:

(17 + 255)/2 = 136

Thus, the number halfway between 17 and 255 is 136.

To check that our answer is correct, we subtract 17 from 136 and subtract 136 from 255 and compare the two numbers:

136 - 17 = 119
255 - 136 = 119

As you can see, the halfway number is 119 higher than 17 and 119 lower than 255. Therefore, our halfway between answer of 136 above is correct.
