Halfway Between 4 and 30

When you ask "What number is halfway between 4 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=4 and Y=30.

Halfway Between Line

To find the number halfway between 4 and 30, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 30 into our formula, we get:

(4 + 30)/2 = 17

Thus, the number halfway between 4 and 30 is 17.

To check that our answer is correct, we subtract 4 from 17 and subtract 17 from 30 and compare the two numbers:

17 - 4 = 13
30 - 17 = 13

As you can see, the halfway number is 13 higher than 4 and 13 lower than 30. Therefore, our halfway between answer of 17 above is correct.
