Halfway Between 12 and 664

When you ask "What number is halfway between 12 and 664?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=12 and Y=664.

Halfway Between Line

To find the number halfway between 12 and 664, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 12 and 664 into our formula, we get:

(12 + 664)/2 = 338

Thus, the number halfway between 12 and 664 is 338.

To check that our answer is correct, we subtract 12 from 338 and subtract 338 from 664 and compare the two numbers:

338 - 12 = 326
664 - 338 = 326

As you can see, the halfway number is 326 higher than 12 and 326 lower than 664. Therefore, our halfway between answer of 338 above is correct.
