Halfway Between 15 and 791

When you ask "What number is halfway between 15 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=15 and Y=791.

Halfway Between Line

To find the number halfway between 15 and 791, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 791 into our formula, we get:

(15 + 791)/2 = 403

Thus, the number halfway between 15 and 791 is 403.

To check that our answer is correct, we subtract 15 from 403 and subtract 403 from 791 and compare the two numbers:

403 - 15 = 388
791 - 403 = 388

As you can see, the halfway number is 388 higher than 15 and 388 lower than 791. Therefore, our halfway between answer of 403 above is correct.
