Halfway Between 100 and 829

When you ask "What number is halfway between 100 and 829?" 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=829.

Halfway Between Line

To find the number halfway between 100 and 829, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 829 into our formula, we get:

(100 + 829)/2 = 464.5

Thus, the number halfway between 100 and 829 is 464.5.

To check that our answer is correct, we subtract 100 from 464.5 and subtract 464.5 from 829 and compare the two numbers:

464.5 - 100 = 364.5
829 - 464.5 = 364.5

As you can see, the halfway number is 364.5 higher than 100 and 364.5 lower than 829. Therefore, our halfway between answer of 464.5 above is correct.
