Halfway Between 9 and 82

When you ask "What number is halfway between 9 and 82?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=9 and Y=82.

Halfway Between Line

To find the number halfway between 9 and 82, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 82 into our formula, we get:

(9 + 82)/2 = 45.5

Thus, the number halfway between 9 and 82 is 45.5.

To check that our answer is correct, we subtract 9 from 45.5 and subtract 45.5 from 82 and compare the two numbers:

45.5 - 9 = 36.5
82 - 45.5 = 36.5

As you can see, the halfway number is 36.5 higher than 9 and 36.5 lower than 82. Therefore, our halfway between answer of 45.5 above is correct.
