Halfway Between 10 and 80

When you ask "What number is halfway between 10 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=10 and Y=80.

Halfway Between Line

To find the number halfway between 10 and 80, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 80 into our formula, we get:

(10 + 80)/2 = 45

Thus, the number halfway between 10 and 80 is 45.

To check that our answer is correct, we subtract 10 from 45 and subtract 45 from 80 and compare the two numbers:

45 - 10 = 35
80 - 45 = 35

As you can see, the halfway number is 35 higher than 10 and 35 lower than 80. Therefore, our halfway between answer of 45 above is correct.
