Halfway Between 10 and 664

When you ask "What number is halfway between 10 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=10 and Y=664.

Halfway Between Line

To find the number halfway between 10 and 664, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 664 into our formula, we get:

(10 + 664)/2 = 337

Thus, the number halfway between 10 and 664 is 337.

To check that our answer is correct, we subtract 10 from 337 and subtract 337 from 664 and compare the two numbers:

337 - 10 = 327
664 - 337 = 327

As you can see, the halfway number is 327 higher than 10 and 327 lower than 664. Therefore, our halfway between answer of 337 above is correct.
