Halfway Between 15 and 255

When you ask "What number is halfway between 15 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=15 and Y=255.

Halfway Between Line

To find the number halfway between 15 and 255, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 255 into our formula, we get:

(15 + 255)/2 = 135

Thus, the number halfway between 15 and 255 is 135.

To check that our answer is correct, we subtract 15 from 135 and subtract 135 from 255 and compare the two numbers:

135 - 15 = 120
255 - 135 = 120

As you can see, the halfway number is 120 higher than 15 and 120 lower than 255. Therefore, our halfway between answer of 135 above is correct.
