Answer:
Incorrect information.
Step-by-step explanation:
According to the information of the problem we have that
[tex]a_n = 6a_{n-1} - 9a_{n-2}[/tex]
[tex]a_0 = 5 \,\,\, , a_1 = 18[/tex]
Notice that if
[tex]a_n = (n+5)3n[/tex]
in fact
[tex]a_2 = 6a_1 - 9a_0 = 6(18)-9(5) = 63[/tex]
and if you explicit formula you are given then
[tex]a_2 = (2+5)3(2) = 42.[/tex]
Therefore the base step is incorrect. And you can not proceed.
