Halfway Between 28 and 642

When you ask "What number is halfway between 28 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=28 and Y=642.

Halfway Between Line

To find the number halfway between 28 and 642, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 28 and 642 into our formula, we get:

(28 + 642)/2 = 335

Thus, the number halfway between 28 and 642 is 335.

To check that our answer is correct, we subtract 28 from 335 and subtract 335 from 642 and compare the two numbers:

335 - 28 = 307
642 - 335 = 307

As you can see, the halfway number is 307 higher than 28 and 307 lower than 642. Therefore, our halfway between answer of 335 above is correct.
