Halfway Between 16 and 628

When you ask "What number is halfway between 16 and 628?" 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=628.

Halfway Between Line

To find the number halfway between 16 and 628, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 16 and 628 into our formula, we get:

(16 + 628)/2 = 322

Thus, the number halfway between 16 and 628 is 322.

To check that our answer is correct, we subtract 16 from 322 and subtract 322 from 628 and compare the two numbers:

322 - 16 = 306
628 - 322 = 306

As you can see, the halfway number is 306 higher than 16 and 306 lower than 628. Therefore, our halfway between answer of 322 above is correct.
