The geometric sequence when the first term is 1/5 and the common ratio is 5 is; f(n) = f(n-1) . 5.
What is the geometric sequence described?
The geometric sequence described in the task content is one whose first term is; f(1) = 1/5.
Additionally, it follows from convention that the recursive function for a geometric sequence is; a product of a previous term and the common ratio.
Hence, we have; f(n) = f(n-1) . 5.
