Answer:
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 2
Step-by-step explanation:
There is a common difference d between consecutive terms
d = 5 - 3 = 7 - 5 = 9 - 7 = 11 - 9 = 2
A recursive formula allows a term in the sequence be found by adding d to the previous term, then
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 2 : with a₁ = 3
