Answer 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.
