What is the sum of the geometric sequence 3 9 27 81 7th term?

1 Answer. Elizabeth P. A geometric sequence has a constant ratio (common ratio) between consecutive terms. Both ways get you to the same answer that the 7th term in that geometric sequence is 2, 187 .

What is the 7th term of the geometric sequence?

The nth term of the geometric sequence is given by: an = a · rn - 1, Where a is the first term and r is the common ratio respectively. Therefore, the 7th term of the geometric sequence a7 is 1/16.

What is the common ratio of the geometric sequence 3 9 27?
