Halfway Between 99 and 673

When you ask "What number is halfway between 99 and 673?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=99 and Y=673.

Halfway Between Line

To find the number halfway between 99 and 673, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 99 and 673 into our formula, we get:

(99 + 673)/2 = 386

Thus, the number halfway between 99 and 673 is 386.

To check that our answer is correct, we subtract 99 from 386 and subtract 386 from 673 and compare the two numbers:

386 - 99 = 287
673 - 386 = 287

As you can see, the halfway number is 287 higher than 99 and 287 lower than 673. Therefore, our halfway between answer of 386 above is correct.
