Halfway Between 20 and 797

When you ask "What number is halfway between 20 and 797?" 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=797.

Halfway Between Line

To find the number halfway between 20 and 797, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 797 into our formula, we get:

(20 + 797)/2 = 408.5

Thus, the number halfway between 20 and 797 is 408.5.

To check that our answer is correct, we subtract 20 from 408.5 and subtract 408.5 from 797 and compare the two numbers:

408.5 - 20 = 388.5
797 - 408.5 = 388.5

As you can see, the halfway number is 388.5 higher than 20 and 388.5 lower than 797. Therefore, our halfway between answer of 408.5 above is correct.
