Halfway Between 20 and 39

When you ask "What number is halfway between 20 and 39?" 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=39.

Halfway Between Line

To find the number halfway between 20 and 39, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 39 into our formula, we get:

(20 + 39)/2 = 29.5

Thus, the number halfway between 20 and 39 is 29.5.

To check that our answer is correct, we subtract 20 from 29.5 and subtract 29.5 from 39 and compare the two numbers:

29.5 - 20 = 9.5
39 - 29.5 = 9.5

As you can see, the halfway number is 9.5 higher than 20 and 9.5 lower than 39. Therefore, our halfway between answer of 29.5 above is correct.
