Halfway Between 13 and 684

When you ask "What number is halfway between 13 and 684?" 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=684.

Halfway Between Line

To find the number halfway between 13 and 684, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 684 into our formula, we get:

(13 + 684)/2 = 348.5

Thus, the number halfway between 13 and 684 is 348.5.

To check that our answer is correct, we subtract 13 from 348.5 and subtract 348.5 from 684 and compare the two numbers:

348.5 - 13 = 335.5
684 - 348.5 = 335.5

As you can see, the halfway number is 335.5 higher than 13 and 335.5 lower than 684. Therefore, our halfway between answer of 348.5 above is correct.
