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!

  • Math - Geometry -

    You are multiplying the previous number by 3.

  • Math - Geometry -

    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)
