Halfway Between 16 and 642

When you ask "What number is halfway between 16 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=16 and Y=642.

Halfway Between Line

To find the number halfway between 16 and 642, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 16 and 642 into our formula, we get:

(16 + 642)/2 = 329

Thus, the number halfway between 16 and 642 is 329.

To check that our answer is correct, we subtract 16 from 329 and subtract 329 from 642 and compare the two numbers:

329 - 16 = 313
642 - 329 = 313

As you can see, the halfway number is 313 higher than 16 and 313 lower than 642. Therefore, our halfway between answer of 329 above is correct.
