Match each sequence with one of the recursive definitions. Note that only the part of the definition showing the relationship between the current term and the previous term is given so as not to give away the solutions. One of the sequences matches two recursive definitions.

7,3,-1,-5
arrow_right_alt
1,-\frac{1}{2},\frac{1}{4},-\frac{1}{8}
arrow_right_alt
