When you ask "What number is halfway between 8 and 49?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=8 and Y=49.
To find the number halfway between 8 and 49, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 8 and 49 into our formula, we get:
(8 + 49)/2 = 28.5
Thus, the number halfway between 8 and 49 is 28.5.
To check that our answer is correct, we subtract 8 from 28.5 and subtract 28.5 from 49 and compare the two numbers:
28.5 - 8 = 20.5
49 - 28.5 = 20.5
As you can see, the halfway number is 20.5 higher than 8 and 20.5 lower than 49. Therefore, our halfway between answer of 28.5 above is correct.
