Halfway Between 20 and 40

When you ask "What number is halfway between 20 and 40?" 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=40.

Halfway Between Line

To find the number halfway between 20 and 40, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 40 into our formula, we get:

(20 + 40)/2 = 30

Thus, the number halfway between 20 and 40 is 30.

To check that our answer is correct, we subtract 20 from 30 and subtract 30 from 40 and compare the two numbers:

30 - 20 = 10
40 - 30 = 10

As you can see, the halfway number is 10 higher than 20 and 10 lower than 40. Therefore, our halfway between answer of 30 above is correct.
