Halfway Between 30 and 66

When you ask "What number is halfway between 30 and 66?" 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=66.

Halfway Between Line

To find the number halfway between 30 and 66, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 66 into our formula, we get:

(30 + 66)/2 = 48

Thus, the number halfway between 30 and 66 is 48.

To check that our answer is correct, we subtract 30 from 48 and subtract 48 from 66 and compare the two numbers:

48 - 30 = 18
66 - 48 = 18

As you can see, the halfway number is 18 higher than 30 and 18 lower than 66. Therefore, our halfway between answer of 48 above is correct.
