Halfway Between 2 and 20

When you ask "What number is halfway between 2 and 20?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=2 and Y=20.

Halfway Between Line

To find the number halfway between 2 and 20, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 2 and 20 into our formula, we get:

(2 + 20)/2 = 11

Thus, the number halfway between 2 and 20 is 11.

To check that our answer is correct, we subtract 2 from 11 and subtract 11 from 20 and compare the two numbers:

11 - 2 = 9
20 - 11 = 9

As you can see, the halfway number is 9 higher than 2 and 9 lower than 20. Therefore, our halfway between answer of 11 above is correct.
