Halfway Between 25 and 30

When you ask "What number is halfway between 25 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=25 and Y=30.

Halfway Between Line

To find the number halfway between 25 and 30, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 25 and 30 into our formula, we get:

(25 + 30)/2 = 27.5

Thus, the number halfway between 25 and 30 is 27.5.

To check that our answer is correct, we subtract 25 from 27.5 and subtract 27.5 from 30 and compare the two numbers:

27.5 - 25 = 2.5
30 - 27.5 = 2.5

As you can see, the halfway number is 2.5 higher than 25 and 2.5 lower than 30. Therefore, our halfway between answer of 27.5 above is correct.
