Answer:
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 2
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = - 1 - (- 3) = 1 - (- 1) = 3 - 1 = 2
A recursive rule allows a term in the sequence to be found by adding d to the previous term, that is
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 2
