Halfway Between 47 and 684

When you ask "What number is halfway between 47 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=47 and Y=684.

Halfway Between Line

To find the number halfway between 47 and 684, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 47 and 684 into our formula, we get:

(47 + 684)/2 = 365.5

Thus, the number halfway between 47 and 684 is 365.5.

To check that our answer is correct, we subtract 47 from 365.5 and subtract 365.5 from 684 and compare the two numbers:

365.5 - 47 = 318.5
684 - 365.5 = 318.5

As you can see, the halfway number is 318.5 higher than 47 and 318.5 lower than 684. Therefore, our halfway between answer of 365.5 above is correct.
