Halfway Between 100 and 683

When you ask "What number is halfway between 100 and 683?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=100 and Y=683.

Halfway Between Line

To find the number halfway between 100 and 683, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 683 into our formula, we get:

(100 + 683)/2 = 391.5

Thus, the number halfway between 100 and 683 is 391.5.

To check that our answer is correct, we subtract 100 from 391.5 and subtract 391.5 from 683 and compare the two numbers:

391.5 - 100 = 291.5
683 - 391.5 = 291.5

As you can see, the halfway number is 291.5 higher than 100 and 291.5 lower than 683. Therefore, our halfway between answer of 391.5 above is correct.
