Answer:
 =
 =  - 4,
 - 4,  = 3
 = 3
Step-by-step explanation:
A recursive formula allows us to find the next term in the sequence from the previous term.
note the difference between the terms in the sequence
= - 13 - ( - 9) = - 9 - (- 5) = - 5 - (- 1)  = - 1 - 3 = - 4
That is to obtain any term in the sequence we subtract 4 from the previous term, hence
 =
 =  - 4,
 - 4,  = 3
 = 3
