Answer:
- a(1) = 11
- a(n) = 4 + a(n-1)
Step-by-step explanation:
The first term shown is 11. The terms have a common difference of 15 -11 = 4.
These values let you write the recursive formula:
[tex]a_1=11\\a_n=4+a_{n-1}[/tex]
__
The common difference is added to the previous term to find the current term.
