Halfway Between 3 and 80

When you ask "What number is halfway between 3 and 80?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=3 and Y=80.

Halfway Between Line

To find the number halfway between 3 and 80, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 3 and 80 into our formula, we get:

(3 + 80)/2 = 41.5

Thus, the number halfway between 3 and 80 is 41.5.

To check that our answer is correct, we subtract 3 from 41.5 and subtract 41.5 from 80 and compare the two numbers:

41.5 - 3 = 38.5
80 - 41.5 = 38.5

As you can see, the halfway number is 38.5 higher than 3 and 38.5 lower than 80. Therefore, our halfway between answer of 41.5 above is correct.
