Halfway Between 9 and 71

When you ask "What number is halfway between 9 and 71?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=9 and Y=71.

Halfway Between Line

To find the number halfway between 9 and 71, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 71 into our formula, we get:

(9 + 71)/2 = 40

Thus, the number halfway between 9 and 71 is 40.

To check that our answer is correct, we subtract 9 from 40 and subtract 40 from 71 and compare the two numbers:

40 - 9 = 31
71 - 40 = 31

As you can see, the halfway number is 31 higher than 9 and 31 lower than 71. Therefore, our halfway between answer of 40 above is correct.
