Halfway Between 13 and 791

When you ask "What number is halfway between 13 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=13 and Y=791.

Halfway Between Line

To find the number halfway between 13 and 791, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 791 into our formula, we get:

(13 + 791)/2 = 402

Thus, the number halfway between 13 and 791 is 402.

To check that our answer is correct, we subtract 13 from 402 and subtract 402 from 791 and compare the two numbers:

402 - 13 = 389
791 - 402 = 389

As you can see, the halfway number is 389 higher than 13 and 389 lower than 791. Therefore, our halfway between answer of 402 above is correct.
