Halfway Between 17 and 989

When you ask "What number is halfway between 17 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=17 and Y=989.

Halfway Between Line

To find the number halfway between 17 and 989, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 989 into our formula, we get:

(17 + 989)/2 = 503

Thus, the number halfway between 17 and 989 is 503.

To check that our answer is correct, we subtract 17 from 503 and subtract 503 from 989 and compare the two numbers:

503 - 17 = 486
989 - 503 = 486

As you can see, the halfway number is 486 higher than 17 and 486 lower than 989. Therefore, our halfway between answer of 503 above is correct.
