When you ask "What number is halfway between 7 and 867?" 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=867.

To find the number halfway between 7 and 867, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 7 and 867 into our formula, we get:
(7 + 867)/2 = 437
Thus, the number halfway between 7 and 867 is 437.
To check that our answer is correct, we subtract 7 from 437 and subtract 437 from 867 and compare the two numbers:
437 - 7 = 430
867 - 437 = 430
As you can see, the halfway number is 430 higher than 7 and 430 lower than 867. Therefore, our halfway between answer of 437 above is correct.
