1.State which sequence is arithmetic and find the common difference of the sequence.
Hence C$_n$ is arithmetic and d=
.
2.State which sequence is geometric and find the common ratio of the sequence.
Hence d$_n$ is geometric and r=
.
3.For the geometric sequence find the exact value of the eighth term. Give your answer as a fraction.
Using the nth term formula d$_n$=
