Halfway Between 20 and 256

When you ask "What number is halfway between 20 and 256?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=20 and Y=256.

Halfway Between Line

To find the number halfway between 20 and 256, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 256 into our formula, we get:

(20 + 256)/2 = 138

Thus, the number halfway between 20 and 256 is 138.

To check that our answer is correct, we subtract 20 from 138 and subtract 138 from 256 and compare the two numbers:

138 - 20 = 118
256 - 138 = 118

As you can see, the halfway number is 118 higher than 20 and 118 lower than 256. Therefore, our halfway between answer of 138 above is correct.
