Halfway Between 12 and 30

When you ask "What number is halfway between 12 and 30?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=12 and Y=30.

Halfway Between Line

To find the number halfway between 12 and 30, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 12 and 30 into our formula, we get:

(12 + 30)/2 = 21

Thus, the number halfway between 12 and 30 is 21.

To check that our answer is correct, we subtract 12 from 21 and subtract 21 from 30 and compare the two numbers:

21 - 12 = 9
30 - 21 = 9

As you can see, the halfway number is 9 higher than 12 and 9 lower than 30. Therefore, our halfway between answer of 21 above is correct.
