Write a recursive process using sequence notation for the geometric sequence {3,9,27,} that can be used to determine the next term. a1 = 3; an = an − 1 + 3, n > 1 a1 = 3; an = an + 3, n > 1 a1 = 3; an = an − 1 ● 3, n > 1 a1 = 3; an = an − 2 + 3, n > 1

We are given

geometric sequence

3,9,27,81,...

we can see that

first term is 3

so,

second term is 9

we can also write it as

we can replace 3 as a1

Similarly , we have

third term is 27

we can also write it as

so, for nth term

for n>1.........Answer
