Halfway Between 30 and 664

When you ask "What number is halfway between 30 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=30 and Y=664.

Halfway Between Line

To find the number halfway between 30 and 664, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 664 into our formula, we get:

(30 + 664)/2 = 347

Thus, the number halfway between 30 and 664 is 347.

To check that our answer is correct, we subtract 30 from 347 and subtract 347 from 664 and compare the two numbers:

347 - 30 = 317
664 - 347 = 317

As you can see, the halfway number is 317 higher than 30 and 317 lower than 664. Therefore, our halfway between answer of 347 above is correct.
