Consider a geometric sequence 
let
and the common ratio be r, then the sequence is constructed as follows:
we can observe that each term of the sequence is its previous term * r.
In the given sequence, to find the common ratio we divide 6,561 by −2,187 and get -3. This means that
Let the first term
,
then the eighth term is
