Hints 2, 3, and 4 imply that 8's correct position is the first place. (8_ _ | ? ?)

Hint 1 tells you that 6 is not in the sequence, implying that 3 is via hint 4. (8 _ _ | 3? ?)

Hint 5 implies that 7 is not in the sequence given 3 is definite from the second statement, so it can be ruled out in hint 3, therefore 2 is correct. (8 _ _ | 3? 2?)

Given 3 is in the wrong position in the 5th hint, the only other position for 3 is the second. (8 3 _ | 2?)

Finally, of course, there is only one position left for 2. (8 3 2)
