Halfway Between 5 and 664

When you ask "What number is halfway between 5 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=5 and Y=664.

Halfway Between Line

To find the number halfway between 5 and 664, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 664 into our formula, we get:

(5 + 664)/2 = 334.5

Thus, the number halfway between 5 and 664 is 334.5.

To check that our answer is correct, we subtract 5 from 334.5 and subtract 334.5 from 664 and compare the two numbers:

334.5 - 5 = 329.5
664 - 334.5 = 329.5

As you can see, the halfway number is 329.5 higher than 5 and 329.5 lower than 664. Therefore, our halfway between answer of 334.5 above is correct.
