Halfway Between 13 and 823

When you ask "What number is halfway between 13 and 823?" 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=823.

Halfway Between Line

To find the number halfway between 13 and 823, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 823 into our formula, we get:

(13 + 823)/2 = 418

Thus, the number halfway between 13 and 823 is 418.

To check that our answer is correct, we subtract 13 from 418 and subtract 418 from 823 and compare the two numbers:

418 - 13 = 405
823 - 418 = 405

As you can see, the halfway number is 405 higher than 13 and 405 lower than 823. Therefore, our halfway between answer of 418 above is correct.
