Halfway Between 20 and 791

When you ask "What number is halfway between 20 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=20 and Y=791.

Halfway Between Line

To find the number halfway between 20 and 791, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 791 into our formula, we get:

(20 + 791)/2 = 405.5

Thus, the number halfway between 20 and 791 is 405.5.

To check that our answer is correct, we subtract 20 from 405.5 and subtract 405.5 from 791 and compare the two numbers:

405.5 - 20 = 385.5
791 - 405.5 = 385.5

As you can see, the halfway number is 385.5 higher than 20 and 385.5 lower than 791. Therefore, our halfway between answer of 405.5 above is correct.
