    Answer:

    a_{n} = 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

    a_{n} = a₁ + (n – 1)d

    where a₁ is the first term and d the common difference

    Here a₁ = 9 and d = 2, thus

    a_{n} = 9 + 2(n – 1) = 9 + 2n – 2 = 2n + 7
