Halfway Between 20 and 805

When you ask "What number is halfway between 20 and 805?" 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=805.

Halfway Between Line

To find the number halfway between 20 and 805, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 805 into our formula, we get:

(20 + 805)/2 = 412.5

Thus, the number halfway between 20 and 805 is 412.5.

To check that our answer is correct, we subtract 20 from 412.5 and subtract 412.5 from 805 and compare the two numbers:

412.5 - 20 = 392.5
805 - 412.5 = 392.5

As you can see, the halfway number is 392.5 higher than 20 and 392.5 lower than 805. Therefore, our halfway between answer of 412.5 above is correct.
