Halfway Between 84 and 255

When you ask "What number is halfway between 84 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=84 and Y=255.

Halfway Between Line

To find the number halfway between 84 and 255, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 84 and 255 into our formula, we get:

(84 + 255)/2 = 169.5

Thus, the number halfway between 84 and 255 is 169.5.

To check that our answer is correct, we subtract 84 from 169.5 and subtract 169.5 from 255 and compare the two numbers:

169.5 - 84 = 85.5
255 - 169.5 = 85.5

As you can see, the halfway number is 85.5 higher than 84 and 85.5 lower than 255. Therefore, our halfway between answer of 169.5 above is correct.
