Halfway Between 30 and 630

When you ask "What number is halfway between 30 and 630?" 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=630.

Halfway Between Line

To find the number halfway between 30 and 630, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 630 into our formula, we get:

(30 + 630)/2 = 330

Thus, the number halfway between 30 and 630 is 330.

To check that our answer is correct, we subtract 30 from 330 and subtract 330 from 630 and compare the two numbers:

330 - 30 = 300
630 - 330 = 300

As you can see, the halfway number is 300 higher than 30 and 300 lower than 630. Therefore, our halfway between answer of 330 above is correct.
