The recursive definition of the geometric sequence is given as follows:

  • [tex]f(1) = \frac{1}{9}[/tex].
  • f(n) = f(n-1) x 3.

What is a geometric sequence?

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

[tex]a_n = a_1q^{n-1}[/tex]

In which [tex]a_1[/tex] is the first term.

The recursive definition of the geometric sequence is given as follows:

  • [tex]f(1) = a_1[/tex].
  • f(n) = q x f(n - 1).

For this sequence, the first term and common ratio are given as follows:

[tex]a_1 = \frac{1}{9}, q = 3[/tex].

Then the recursive definition is:

  • [tex]f(1) = \frac{1}{9}[/tex].
  • f(n) = f(n-1) x 3.
