Halfway Between 9 and 799

When you ask "What number is halfway between 9 and 799?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=9 and Y=799.

Halfway Between Line

To find the number halfway between 9 and 799, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 799 into our formula, we get:

(9 + 799)/2 = 404

Thus, the number halfway between 9 and 799 is 404.

To check that our answer is correct, we subtract 9 from 404 and subtract 404 from 799 and compare the two numbers:

404 - 9 = 395
799 - 404 = 395

As you can see, the halfway number is 395 higher than 9 and 395 lower than 799. Therefore, our halfway between answer of 404 above is correct.
