Halfway Between 81 and 791

When you ask "What number is halfway between 81 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=81 and Y=791.

Halfway Between Line

To find the number halfway between 81 and 791, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 81 and 791 into our formula, we get:

(81 + 791)/2 = 436

Thus, the number halfway between 81 and 791 is 436.

To check that our answer is correct, we subtract 81 from 436 and subtract 436 from 791 and compare the two numbers:

436 - 81 = 355
791 - 436 = 355

As you can see, the halfway number is 355 higher than 81 and 355 lower than 791. Therefore, our halfway between answer of 436 above is correct.
