When you ask "What number is halfway between 49 and 869?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=49 and Y=869.

To find the number halfway between 49 and 869, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 49 and 869 into our formula, we get:
(49 + 869)/2 = 459
Thus, the number halfway between 49 and 869 is 459.
To check that our answer is correct, we subtract 49 from 459 and subtract 459 from 869 and compare the two numbers:
459 - 49 = 410
869 - 459 = 410
As you can see, the halfway number is 410 higher than 49 and 410 lower than 869. Therefore, our halfway between answer of 459 above is correct.
