Halfway Between 15 and 683

When you ask "What number is halfway between 15 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=15 and Y=683.

Halfway Between Line

To find the number halfway between 15 and 683, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 683 into our formula, we get:

(15 + 683)/2 = 349

Thus, the number halfway between 15 and 683 is 349.

To check that our answer is correct, we subtract 15 from 349 and subtract 349 from 683 and compare the two numbers:

349 - 15 = 334
683 - 349 = 334

As you can see, the halfway number is 334 higher than 15 and 334 lower than 683. Therefore, our halfway between answer of 349 above is correct.
