The recursive definition for the geometric sequence is given as follows:
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:
In which is the first term.
The recursive definition of a geometric sequence is given by:
In this problem, we have that the first term and the common ratio are given, respectively, by:
.
Hence the recursive definition is given by:

Answer:
x ≈ 11.09
Step-by-step explanation:
Using the rule of logarithms
x = n ⇒ x =
Given
ln(x + 9) = 3 , that is
(x + 9) = 3 , then
x + 9 = e³ ( subtract 9 from both sides )
x = e³ - 9 ≈ 11.09 ( to the nearest hundredth )
