Answer:25

Step-by-step explanation:THIS IS FILLING IN THE CHARACTERS and i got this by adding by 2

Answer:= 2n + 7

Step-by-step explanation:There is a common difference d between consecutive terms of the sequence

d = 11 – 9 = 13 – 11 = 15 – 13 = 17 – 15 = 2

This indicates the sequence is arithmetic with n th term

= a₁ + (n – 1)d

where a₁ is the first term and d the common difference

Here a₁ = 9 and d = 2, thus

= 9 + 2(n – 1) = 9 + 2n – 2 = 2n + 7
