    Putri is correct

    This is an arithmetic sequence, whose n th term is

    a_{n} = a_{1} + (n – 1 )d

    where a_{1} is the first term and d the common difference

    d = – 17 – (- 34 ) = – 34 – (- 51) = 17 and a_{1} = – 51, hence

    a_{n} = – 51 + 17(n – 1) = – 51 + 17n – 17 = 17n – 68 ← Putri
