Halfway Between 30 and 330

When you ask "What number is halfway between 30 and 330?" 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=330.

Halfway Between Line

To find the number halfway between 30 and 330, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 330 into our formula, we get:

(30 + 330)/2 = 180

Thus, the number halfway between 30 and 330 is 180.

To check that our answer is correct, we subtract 30 from 180 and subtract 180 from 330 and compare the two numbers:

180 - 30 = 150
330 - 180 = 150

As you can see, the halfway number is 150 higher than 30 and 150 lower than 330. Therefore, our halfway between answer of 180 above is correct.
