Halfway Between 13 and 815

When you ask "What number is halfway between 13 and 815?" 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=815.

Halfway Between Line

To find the number halfway between 13 and 815, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 815 into our formula, we get:

(13 + 815)/2 = 414

Thus, the number halfway between 13 and 815 is 414.

To check that our answer is correct, we subtract 13 from 414 and subtract 414 from 815 and compare the two numbers:

414 - 13 = 401
815 - 414 = 401

As you can see, the halfway number is 401 higher than 13 and 401 lower than 815. Therefore, our halfway between answer of 414 above is correct.
