Introduction to definition, identification, and general term of geometric sequences
A sequence is geometric if the ratio between consecutive terms is always constant, i.e.
We call r the common ratio.
For instance, the sequence
is geometric with r=41, but
is not since 69=23=2=36.
The nth term of a geometric sequence is given by
where u1 is the first term and r is the common ratio.
Nice work completing Geometric Sequences, here's a quick recap of what we covered:
