Halfway Between 9 and 791

When you ask "What number is halfway between 9 and 791?" 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=791.

Halfway Between Line

To find the number halfway between 9 and 791, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 791 into our formula, we get:

(9 + 791)/2 = 400

Thus, the number halfway between 9 and 791 is 400.

To check that our answer is correct, we subtract 9 from 400 and subtract 400 from 791 and compare the two numbers:

400 - 9 = 391
791 - 400 = 391

As you can see, the halfway number is 391 higher than 9 and 391 lower than 791. Therefore, our halfway between answer of 400 above is correct.
