Halfway Between 13 and 991

When you ask "What number is halfway between 13 and 991?" 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=991.

Halfway Between Line

To find the number halfway between 13 and 991, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 991 into our formula, we get:

(13 + 991)/2 = 502

Thus, the number halfway between 13 and 991 is 502.

To check that our answer is correct, we subtract 13 from 502 and subtract 502 from 991 and compare the two numbers:

502 - 13 = 489
991 - 502 = 489

As you can see, the halfway number is 489 higher than 13 and 489 lower than 991. Therefore, our halfway between answer of 502 above is correct.
