Answer:
[tex]a_n=a_{n-1}+11[/tex]
Step-by-step explanation:
From inspection of the sequence of numbers, we can see that each term is the previous term plus 11.
10 + 11 = 21
21 + 11 = 32
32 + 11 = 43
etc.
[tex]a_n[/tex] is the term
[tex]a_{n-1}[/tex] is the previous term
Therefore,
[tex]a_n=a_{n-1}+11[/tex]
