Halfway Between 30 and 72

When you ask "What number is halfway between 30 and 72?" 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=72.

Halfway Between Line

To find the number halfway between 30 and 72, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 72 into our formula, we get:

(30 + 72)/2 = 51

Thus, the number halfway between 30 and 72 is 51.

To check that our answer is correct, we subtract 30 from 51 and subtract 51 from 72 and compare the two numbers:

51 - 30 = 21
72 - 51 = 21

As you can see, the halfway number is 21 higher than 30 and 21 lower than 72. Therefore, our halfway between answer of 51 above is correct.
