Halfway Between 77 and 255

When you ask "What number is halfway between 77 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=77 and Y=255.

Halfway Between Line

To find the number halfway between 77 and 255, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 255 into our formula, we get:

(77 + 255)/2 = 166

Thus, the number halfway between 77 and 255 is 166.

To check that our answer is correct, we subtract 77 from 166 and subtract 166 from 255 and compare the two numbers:

166 - 77 = 89
255 - 166 = 89

As you can see, the halfway number is 89 higher than 77 and 89 lower than 255. Therefore, our halfway between answer of 166 above is correct.
