Halfway Between 17 and 791

When you ask "What number is halfway between 17 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=17 and Y=791.

Halfway Between Line

To find the number halfway between 17 and 791, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 791 into our formula, we get:

(17 + 791)/2 = 404

Thus, the number halfway between 17 and 791 is 404.

To check that our answer is correct, we subtract 17 from 404 and subtract 404 from 791 and compare the two numbers:

404 - 17 = 387
791 - 404 = 387

As you can see, the halfway number is 387 higher than 17 and 387 lower than 791. Therefore, our halfway between answer of 404 above is correct.
