Halfway Between 51 and 82

When you ask "What number is halfway between 51 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=51 and Y=82.

Halfway Between Line

To find the number halfway between 51 and 82, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 51 and 82 into our formula, we get:

(51 + 82)/2 = 66.5

Thus, the number halfway between 51 and 82 is 66.5.

To check that our answer is correct, we subtract 51 from 66.5 and subtract 66.5 from 82 and compare the two numbers:

66.5 - 51 = 15.5
82 - 66.5 = 15.5

As you can see, the halfway number is 15.5 higher than 51 and 15.5 lower than 82. Therefore, our halfway between answer of 66.5 above is correct.
