Halfway Between 30 and 829

When you ask "What number is halfway between 30 and 829?" 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=829.

Halfway Between Line

To find the number halfway between 30 and 829, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 829 into our formula, we get:

(30 + 829)/2 = 429.5

Thus, the number halfway between 30 and 829 is 429.5.

To check that our answer is correct, we subtract 30 from 429.5 and subtract 429.5 from 829 and compare the two numbers:

429.5 - 30 = 399.5
829 - 429.5 = 399.5

As you can see, the halfway number is 399.5 higher than 30 and 399.5 lower than 829. Therefore, our halfway between answer of 429.5 above is correct.
