Halfway Between 30 and 90

When you ask "What number is halfway between 30 and 90?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=30 and Y=90.

Halfway Between Line

To find the number halfway between 30 and 90, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 90 into our formula, we get:

(30 + 90)/2 = 60

Thus, the number halfway between 30 and 90 is 60.

To check that our answer is correct, we subtract 30 from 60 and subtract 60 from 90 and compare the two numbers:

60 - 30 = 30
90 - 60 = 30

As you can see, the halfway number is 30 higher than 30 and 30 lower than 90. Therefore, our halfway between answer of 60 above is correct.
