No 6n Does Not end with Digit 5
Reason:
6n is a multiple of 6
The Factors of 6 are 2 and 3
Multiple of 2 end with even digits
Multiples of 3 end with odd number it may have 5 as last digit
The Both factors have last digit as 5 then 6 can end with 5 But this is a hypothetical case.
So 6n cannot have 5 as its last digit
