Halfway Between 19 and 80

When you ask "What number is halfway between 19 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=19 and Y=80.

Halfway Between Line

To find the number halfway between 19 and 80, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 19 and 80 into our formula, we get:

(19 + 80)/2 = 49.5

Thus, the number halfway between 19 and 80 is 49.5.

To check that our answer is correct, we subtract 19 from 49.5 and subtract 49.5 from 80 and compare the two numbers:

49.5 - 19 = 30.5
80 - 49.5 = 30.5

As you can see, the halfway number is 30.5 higher than 19 and 30.5 lower than 80. Therefore, our halfway between answer of 49.5 above is correct.
