Halfway Between 2 and 642

When you ask "What number is halfway between 2 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=2 and Y=642.

Halfway Between Line

To find the number halfway between 2 and 642, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 2 and 642 into our formula, we get:

(2 + 642)/2 = 322

Thus, the number halfway between 2 and 642 is 322.

To check that our answer is correct, we subtract 2 from 322 and subtract 322 from 642 and compare the two numbers:

322 - 2 = 320
642 - 322 = 320

As you can see, the halfway number is 320 higher than 2 and 320 lower than 642. Therefore, our halfway between answer of 322 above is correct.
