    First determine whether arithmetic sequence or geometric

    both seem to be arithmetic

    first one

    adds 9

    starts with - 7

    an=a1 + (n-1) d

    a1=first term

    d=common difference

    an=-7+9 (n-1)

    51 term is

    a51=-7+9 (51-1)

    a51=-7+9 (50)

    a51=-7+450

    a51=443

    51term is 443

    adds 6 every times

    starts with - 9

    an=-9+6 (n-1)

    22nd term

    a22=-9+6 (22-1)

    a22=-9+126

    a22=117

    22nt term is 117
