Halfway Between 66 and 680

When you ask "What number is halfway between 66 and 680?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=66 and Y=680.

Halfway Between Line

To find the number halfway between 66 and 680, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 680 into our formula, we get:

(66 + 680)/2 = 373

Thus, the number halfway between 66 and 680 is 373.

To check that our answer is correct, we subtract 66 from 373 and subtract 373 from 680 and compare the two numbers:

373 - 66 = 307
680 - 373 = 307

As you can see, the halfway number is 307 higher than 66 and 307 lower than 680. Therefore, our halfway between answer of 373 above is correct.
