Halfway Between 13 and 813

When you ask "What number is halfway between 13 and 813?" 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=813.

Halfway Between Line

To find the number halfway between 13 and 813, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 813 into our formula, we get:

(13 + 813)/2 = 413

Thus, the number halfway between 13 and 813 is 413.

To check that our answer is correct, we subtract 13 from 413 and subtract 413 from 813 and compare the two numbers:

413 - 13 = 400
813 - 413 = 400

As you can see, the halfway number is 400 higher than 13 and 400 lower than 813. Therefore, our halfway between answer of 413 above is correct.
