Halfway Between 66 and 668

When you ask "What number is halfway between 66 and 668?" 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=668.

Halfway Between Line

To find the number halfway between 66 and 668, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 668 into our formula, we get:

(66 + 668)/2 = 367

Thus, the number halfway between 66 and 668 is 367.

To check that our answer is correct, we subtract 66 from 367 and subtract 367 from 668 and compare the two numbers:

367 - 66 = 301
668 - 367 = 301

As you can see, the halfway number is 301 higher than 66 and 301 lower than 668. Therefore, our halfway between answer of 367 above is correct.
