Halfway Between 13 and 989

When you ask "What number is halfway between 13 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=13 and Y=989.

Halfway Between Line

To find the number halfway between 13 and 989, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 989 into our formula, we get:

(13 + 989)/2 = 501

Thus, the number halfway between 13 and 989 is 501.

To check that our answer is correct, we subtract 13 from 501 and subtract 501 from 989 and compare the two numbers:

501 - 13 = 488
989 - 501 = 488

As you can see, the halfway number is 488 higher than 13 and 488 lower than 989. Therefore, our halfway between answer of 501 above is correct.
