Halfway Between 4 and 684

When you ask "What number is halfway between 4 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=4 and Y=684.

Halfway Between Line

To find the number halfway between 4 and 684, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 684 into our formula, we get:

(4 + 684)/2 = 344

Thus, the number halfway between 4 and 684 is 344.

To check that our answer is correct, we subtract 4 from 344 and subtract 344 from 684 and compare the two numbers:

344 - 4 = 340
684 - 344 = 340

As you can see, the halfway number is 340 higher than 4 and 340 lower than 684. Therefore, our halfway between answer of 344 above is correct.
