Halfway Between 45 and 82

When you ask "What number is halfway between 45 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=45 and Y=82.

Halfway Between Line

To find the number halfway between 45 and 82, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 82 into our formula, we get:

(45 + 82)/2 = 63.5

Thus, the number halfway between 45 and 82 is 63.5.

To check that our answer is correct, we subtract 45 from 63.5 and subtract 63.5 from 82 and compare the two numbers:

63.5 - 45 = 18.5
82 - 63.5 = 18.5

As you can see, the halfway number is 18.5 higher than 45 and 18.5 lower than 82. Therefore, our halfway between answer of 63.5 above is correct.
