Answer:
[tex]a_{n}[/tex] = 35 - 13n
Step-by-step explanation:
Assuming you require the n th term formula
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n- 1)d
where a₁ is the first term and d the common difference
Here a₁ = 22 and d = - 13, thus
[tex]a_{n}[/tex] = 22 - 13(n - 1) = 22 - 13n + 13 = 35 - 13n
