Halfway Between 1 and 999

When you ask "What number is halfway between 1 and 999?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=1 and Y=999.

Halfway Between Line

To find the number halfway between 1 and 999, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 999 into our formula, we get:

(1 + 999)/2 = 500

Thus, the number halfway between 1 and 999 is 500.

To check that our answer is correct, we subtract 1 from 500 and subtract 500 from 999 and compare the two numbers:

500 - 1 = 499
999 - 500 = 499

As you can see, the halfway number is 499 higher than 1 and 499 lower than 999. Therefore, our halfway between answer of 500 above is correct.
