Halfway Between 20 and 668

When you ask "What number is halfway between 20 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=20 and Y=668.

Halfway Between Line

To find the number halfway between 20 and 668, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 668 into our formula, we get:

(20 + 668)/2 = 344

Thus, the number halfway between 20 and 668 is 344.

To check that our answer is correct, we subtract 20 from 344 and subtract 344 from 668 and compare the two numbers:

344 - 20 = 324
668 - 344 = 324

As you can see, the halfway number is 324 higher than 20 and 324 lower than 668. Therefore, our halfway between answer of 344 above is correct.
