7) is not an arithmetic sequence...
9) 
10) 
Step-by-step explanation:
7 is not an arithmetic sequence because consecutive terms of the sequence do not have a constant common difference.
9 has a first term of 0.5 and has a common ratio of 4 (the quotient between the second term and first, then third term and second, etc.). Thus, your equation is 
10 has a first term of -0.25 and has a common ratio of -8 (the quotient between the second term and first, then third term and second, etc.). Thus, your equation is
