Halfway Between 20 and 684

When you ask "What number is halfway between 20 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=20 and Y=684.

Halfway Between Line

To find the number halfway between 20 and 684, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 684 into our formula, we get:

(20 + 684)/2 = 352

Thus, the number halfway between 20 and 684 is 352.

To check that our answer is correct, we subtract 20 from 352 and subtract 352 from 684 and compare the two numbers:

352 - 20 = 332
684 - 352 = 332

As you can see, the halfway number is 332 higher than 20 and 332 lower than 684. Therefore, our halfway between answer of 352 above is correct.
