Halfway Between 11 and 809

When you ask "What number is halfway between 11 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=11 and Y=809.

Halfway Between Line

To find the number halfway between 11 and 809, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 809 into our formula, we get:

(11 + 809)/2 = 410

Thus, the number halfway between 11 and 809 is 410.

To check that our answer is correct, we subtract 11 from 410 and subtract 410 from 809 and compare the two numbers:

410 - 11 = 399
809 - 410 = 399

As you can see, the halfway number is 399 higher than 11 and 399 lower than 809. Therefore, our halfway between answer of 410 above is correct.
