Halfway Between 65 and 80

When you ask "What number is halfway between 65 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=65 and Y=80.

Halfway Between Line

To find the number halfway between 65 and 80, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 65 and 80 into our formula, we get:

(65 + 80)/2 = 72.5

Thus, the number halfway between 65 and 80 is 72.5.

To check that our answer is correct, we subtract 65 from 72.5 and subtract 72.5 from 80 and compare the two numbers:

72.5 - 65 = 7.5
80 - 72.5 = 7.5

As you can see, the halfway number is 7.5 higher than 65 and 7.5 lower than 80. Therefore, our halfway between answer of 72.5 above is correct.
