Halfway Between 15 and 673

When you ask "What number is halfway between 15 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=15 and Y=673.

Halfway Between Line

To find the number halfway between 15 and 673, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 673 into our formula, we get:

(15 + 673)/2 = 344

Thus, the number halfway between 15 and 673 is 344.

To check that our answer is correct, we subtract 15 from 344 and subtract 344 from 673 and compare the two numbers:

344 - 15 = 329
673 - 344 = 329

As you can see, the halfway number is 329 higher than 15 and 329 lower than 673. Therefore, our halfway between answer of 344 above is correct.
