Halfway Between 12 and 642

When you ask "What number is halfway between 12 and 642?" 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=642.

Halfway Between Line

To find the number halfway between 12 and 642, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 12 and 642 into our formula, we get:

(12 + 642)/2 = 327

Thus, the number halfway between 12 and 642 is 327.

To check that our answer is correct, we subtract 12 from 327 and subtract 327 from 642 and compare the two numbers:

327 - 12 = 315
642 - 327 = 315

As you can see, the halfway number is 315 higher than 12 and 315 lower than 642. Therefore, our halfway between answer of 327 above is correct.
