Halfway Between 21 and 673

When you ask "What number is halfway between 21 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=21 and Y=673.

Halfway Between Line

To find the number halfway between 21 and 673, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 673 into our formula, we get:

(21 + 673)/2 = 347

Thus, the number halfway between 21 and 673 is 347.

To check that our answer is correct, we subtract 21 from 347 and subtract 347 from 673 and compare the two numbers:

347 - 21 = 326
673 - 347 = 326

As you can see, the halfway number is 326 higher than 21 and 326 lower than 673. Therefore, our halfway between answer of 347 above is correct.
