Halfway Between 9 and 997

When you ask "What number is halfway between 9 and 997?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=9 and Y=997.

Halfway Between Line

To find the number halfway between 9 and 997, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 997 into our formula, we get:

(9 + 997)/2 = 503

Thus, the number halfway between 9 and 997 is 503.

To check that our answer is correct, we subtract 9 from 503 and subtract 503 from 997 and compare the two numbers:

503 - 9 = 494
997 - 503 = 494

As you can see, the halfway number is 494 higher than 9 and 494 lower than 997. Therefore, our halfway between answer of 503 above is correct.
