Halfway Between 100 and 791

When you ask "What number is halfway between 100 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=100 and Y=791.

Halfway Between Line

To find the number halfway between 100 and 791, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 791 into our formula, we get:

(100 + 791)/2 = 445.5

Thus, the number halfway between 100 and 791 is 445.5.

To check that our answer is correct, we subtract 100 from 445.5 and subtract 445.5 from 791 and compare the two numbers:

445.5 - 100 = 345.5
791 - 445.5 = 345.5

As you can see, the halfway number is 345.5 higher than 100 and 345.5 lower than 791. Therefore, our halfway between answer of 445.5 above is correct.
