II The common ratio for this sequence is 3. this is not an arithmetic sequence because you need to multiply by 3 and arithmetic sequences you can only add and subtract. the next term would not be 54 because 27*3 is 81. n describes the nth term of the sequence. so if n was 1, 1+ 3 is for and we already know that the 1st term is equal to 1. Therefore, II is the correct answer.
