When you ask "What number is halfway between 7 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=7 and Y=71.

To find the number halfway between 7 and 71, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 7 and 71 into our formula, we get:
(7 + 71)/2 = 39
Thus, the number halfway between 7 and 71 is 39.
To check that our answer is correct, we subtract 7 from 39 and subtract 39 from 71 and compare the two numbers:
39 - 7 = 32
71 - 39 = 32
As you can see, the halfway number is 32 higher than 7 and 32 lower than 71. Therefore, our halfway between answer of 39 above is correct.
