Halfway Between 90 and 672

When you ask "What number is halfway between 90 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=90 and Y=672.

Halfway Between Line

To find the number halfway between 90 and 672, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 672 into our formula, we get:

(90 + 672)/2 = 381

Thus, the number halfway between 90 and 672 is 381.

To check that our answer is correct, we subtract 90 from 381 and subtract 381 from 672 and compare the two numbers:

381 - 90 = 291
672 - 381 = 291

As you can see, the halfway number is 291 higher than 90 and 291 lower than 672. Therefore, our halfway between answer of 381 above is correct.
