Halfway Between 12 and 648

When you ask "What number is halfway between 12 and 648?" 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=648.

Halfway Between Line

To find the number halfway between 12 and 648, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 12 and 648 into our formula, we get:

(12 + 648)/2 = 330

Thus, the number halfway between 12 and 648 is 330.

To check that our answer is correct, we subtract 12 from 330 and subtract 330 from 648 and compare the two numbers:

330 - 12 = 318
648 - 330 = 318

As you can see, the halfway number is 318 higher than 12 and 318 lower than 648. Therefore, our halfway between answer of 330 above is correct.
