Halfway Between 21 and 985

When you ask "What number is halfway between 21 and 985?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=21 and Y=985.

Halfway Between Line

To find the number halfway between 21 and 985, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 985 into our formula, we get:

(21 + 985)/2 = 503

Thus, the number halfway between 21 and 985 is 503.

To check that our answer is correct, we subtract 21 from 503 and subtract 503 from 985 and compare the two numbers:

503 - 21 = 482
985 - 503 = 482

As you can see, the halfway number is 482 higher than 21 and 482 lower than 985. Therefore, our halfway between answer of 503 above is correct.
