Answer 1

domain for "n" means what all values of "n" you can put into that equation

well "n" represents "which term"
like "n=1" means the 1st term
"n=3" means the 3rd term
so "n" has to be greater than "0" because we don't say like "0th term" or "-1th term"
and like this "n" can only be an integer because we don't say like "1.5th term"
