Answer:

[tex]a_{n}[/tex] = 2n + 7

Step-by-step explanation:

There is a common difference d between consecutive terms of the sequence

d = 11 - 9 = 13 - 11 = 15 - 13 = 17 - 15 = 2

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 9 and d = 2, thus

[tex]a_{n}[/tex] = 9 + 2(n - 1) = 9 + 2n - 2 = 2n + 7
