Please help! Need to find the 6th and nth terms in this sequence - and solve for the rule or process.

here's the sequence:

1,3,9,27,81

What is the process or formula to get the nth term in the sequence.

Thanks!

Numebers is previous number multiplied with 3

6th term 81*3=243

nth term

an=a*r^(n-1) Remark: a=1 , r=3

an=1*3^(n-1)

an=3^(n-1)
