  1. #1
    Aren't the terms decreasing by 8 ?
    So after 6 , you would have -2, -10, -18

    #2
    aren't the terms increasing by 3 each time ???
    So how can you possibly get 14 as the next number after 12 ???

    #3 I am puzzled by your choices
    you started with
    -1, 9, 19, 29, adding 10 each time

    what is 29+10 ????
    etc.
