    It's minus 9 at every step
    51 - 9 =42
    42 - 9 = 33
    33 - 9 = 24
    24 - 9 = 15
    15 - 9 = 6 which is your nth term.

    51-9==42
    42-9==33
    33-9==24
    24-9==15
    15-9==6
    6-9==-3
    -3-9=-12
    -12-9=-21
    -21-9=-30

    nth term for 51, 42, 33, 24, 15

    Tn = a + (n - 1) d

    a = 51

    d = 42 - 51 = -9

    Tn = 51 + (n - 1) x -9

    Tn = 51 - 9n + 9

    Tn = 60 - 9n   (This is the Answer)

    It can also be written as Un = 60 - 9n

    nth term of this series should be... 60 - 9n
