Halfway Between 17 and 80

When you ask "What number is halfway between 17 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=17 and Y=80.

Halfway Between Line

To find the number halfway between 17 and 80, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 80 into our formula, we get:

(17 + 80)/2 = 48.5

Thus, the number halfway between 17 and 80 is 48.5.

To check that our answer is correct, we subtract 17 from 48.5 and subtract 48.5 from 80 and compare the two numbers:

48.5 - 17 = 31.5
80 - 48.5 = 31.5

As you can see, the halfway number is 31.5 higher than 17 and 31.5 lower than 80. Therefore, our halfway between answer of 48.5 above is correct.
