Halfway Between 30 and 816

When you ask "What number is halfway between 30 and 816?" 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=816.

Halfway Between Line

To find the number halfway between 30 and 816, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 816 into our formula, we get:

(30 + 816)/2 = 423

Thus, the number halfway between 30 and 816 is 423.

To check that our answer is correct, we subtract 30 from 423 and subtract 423 from 816 and compare the two numbers:

423 - 30 = 393
816 - 423 = 393

As you can see, the halfway number is 393 higher than 30 and 393 lower than 816. Therefore, our halfway between answer of 423 above is correct.
