Halfway Between 11 and 989

When you ask "What number is halfway between 11 and 989?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=11 and Y=989.

Halfway Between Line

To find the number halfway between 11 and 989, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 989 into our formula, we get:

(11 + 989)/2 = 500

Thus, the number halfway between 11 and 989 is 500.

To check that our answer is correct, we subtract 11 from 500 and subtract 500 from 989 and compare the two numbers:

500 - 11 = 489
989 - 500 = 489

As you can see, the halfway number is 489 higher than 11 and 489 lower than 989. Therefore, our halfway between answer of 500 above is correct.
