    Answer:

    see explanation

    Step-by-step explanation:

    These are the terms of an arithmetic sequence

    The n th term ( explicit rule ) for an arithmetic sequence is

    a_{n} = a₁ + (n – 1)d

    where a₁ is the first term and d the common difference

    d = 9 – 2 = 16 – 9 = 23 – 16 = 30 – 23 = 7 and a₁ = 2, hence

    a_{n} = 2 + 7(n – 1) = 2 + 7n – 7 = 7n – 5
