Halfway Between 13 and 809

When you ask "What number is halfway between 13 and 809?" 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=809.

Halfway Between Line

To find the number halfway between 13 and 809, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 809 into our formula, we get:

(13 + 809)/2 = 411

Thus, the number halfway between 13 and 809 is 411.

To check that our answer is correct, we subtract 13 from 411 and subtract 411 from 809 and compare the two numbers:

411 - 13 = 398
809 - 411 = 398

As you can see, the halfway number is 398 higher than 13 and 398 lower than 809. Therefore, our halfway between answer of 411 above is correct.
