Halfway Between 45 and 668

When you ask "What number is halfway between 45 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=45 and Y=668.

Halfway Between Line

To find the number halfway between 45 and 668, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 668 into our formula, we get:

(45 + 668)/2 = 356.5

Thus, the number halfway between 45 and 668 is 356.5.

To check that our answer is correct, we subtract 45 from 356.5 and subtract 356.5 from 668 and compare the two numbers:

356.5 - 45 = 311.5
668 - 356.5 = 311.5

As you can see, the halfway number is 311.5 higher than 45 and 311.5 lower than 668. Therefore, our halfway between answer of 356.5 above is correct.
