Answer:
[tex]a_{5} = 96[/tex].
Step-by-step explanation:
Given : [tex]a_{n} = n^{3} +n^{2} -9n -9[/tex].
To find : What is the fifth term of the sequence .
Solution : We have given [tex]a_{n} = n^{3} +n^{2} -9n -9[/tex].
For n = 5
[tex]a_{5} = 5^{3} +5^{2} -9(5) -9[/tex].
Open the cubes and squares
[tex]a_{5} = 125 + 25 - 45 -9[/tex].
Add the terms
[tex]a_{5} = 96[/tex]..
Therefore, [tex]a_{5} = 96[/tex].
