Halfway Between 18 and 672

When you ask "What number is halfway between 18 and 672?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=18 and Y=672.

Halfway Between Line

To find the number halfway between 18 and 672, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 18 and 672 into our formula, we get:

(18 + 672)/2 = 345

Thus, the number halfway between 18 and 672 is 345.

To check that our answer is correct, we subtract 18 from 345 and subtract 345 from 672 and compare the two numbers:

345 - 18 = 327
672 - 345 = 327

As you can see, the halfway number is 327 higher than 18 and 327 lower than 672. Therefore, our halfway between answer of 345 above is correct.
