Question

First term is is 22 and the common difference is -13

Answer 1

`a_(n)` = 35 - 13n

Explanation:

Assuming you require the n th term formula

The n th term of an arithmetic sequence is

`a_(n)` = a₁ + (n- 1)d

where a₁ is the first term and d the common difference

Here a₁ = 22 and d = - 13, thus

`a_(n)` = 22 - 13(n - 1) = 22 - 13n + 13 = 35 - 13n
