1, 2, 3, 4

-16, -7, 2, 11

As we can see each number is being increased by 9. 

Our recursive 
formula is:

[tex]a(n) = a(n -34) + 9[/tex]

Answer:

[tex]a_{n+1} =a_n+9[/tex]

Step-by-step explanation:

Given is an arithmetic sequence as -16,-7,2,11

We find that

-16+9 =-7

-7+9 =2

2+9 =11

Thus this is an arithmetic sequence with common difference 9

Each term is got by adding 9 to the preceding term

Hence recursive formula is

[tex]a_{n+1} =a_n+9[/tex]
