Halfway Between 13 and 911

When you ask "What number is halfway between 13 and 911?" 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=911.

Halfway Between Line

To find the number halfway between 13 and 911, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 911 into our formula, we get:

(13 + 911)/2 = 462

Thus, the number halfway between 13 and 911 is 462.

To check that our answer is correct, we subtract 13 from 462 and subtract 462 from 911 and compare the two numbers:

462 - 13 = 449
911 - 462 = 449

As you can see, the halfway number is 449 higher than 13 and 449 lower than 911. Therefore, our halfway between answer of 462 above is correct.
