No, it can't end with 5 as if we put any no. in place of n then it will always end with 6 as its cyclicity is 5. i.e. it will repeat it's digits after every interval.
6×1 = 6. [unit digit is 6]
6×2 = 12. [unit digit is 2]
6×3 = 18. [unit digit is 8]
6×4 = 24. [unit digit is 4]
6×5 =30. [unit digit is 0]
6×6 = 36. [unit digit is 6]
hence up to 5 it is unique but after that it is repeating itself.
