Halfway Between 4 and 80

When you ask "What number is halfway between 4 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=4 and Y=80.

Halfway Between Line

To find the number halfway between 4 and 80, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 80 into our formula, we get:

(4 + 80)/2 = 42

Thus, the number halfway between 4 and 80 is 42.

To check that our answer is correct, we subtract 4 from 42 and subtract 42 from 80 and compare the two numbers:

42 - 4 = 38
80 - 42 = 38

As you can see, the halfway number is 38 higher than 4 and 38 lower than 80. Therefore, our halfway between answer of 42 above is correct.
