Halfway Between 40 and 255

When you ask "What number is halfway between 40 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=40 and Y=255.

Halfway Between Line

To find the number halfway between 40 and 255, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 255 into our formula, we get:

(40 + 255)/2 = 147.5

Thus, the number halfway between 40 and 255 is 147.5.

To check that our answer is correct, we subtract 40 from 147.5 and subtract 147.5 from 255 and compare the two numbers:

147.5 - 40 = 107.5
255 - 147.5 = 107.5

As you can see, the halfway number is 107.5 higher than 40 and 107.5 lower than 255. Therefore, our halfway between answer of 147.5 above is correct.
