Halfway Between 3 and 999

When you ask "What number is halfway between 3 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=3 and Y=999.

Halfway Between Line

To find the number halfway between 3 and 999, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 3 and 999 into our formula, we get:

(3 + 999)/2 = 501

Thus, the number halfway between 3 and 999 is 501.

To check that our answer is correct, we subtract 3 from 501 and subtract 501 from 999 and compare the two numbers:

501 - 3 = 498
999 - 501 = 498

As you can see, the halfway number is 498 higher than 3 and 498 lower than 999. Therefore, our halfway between answer of 501 above is correct.
