Question

Please help lol, I have 1 question left after this one

Answer 1

see explanation

Explanation:

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 = 9 and d = - 2, hence

`a_(n)` = 9 -2(n - 1) = 9 - 2n + 2 = - 2n + 11

`a_(n)` = - 2n + 11 ← n th term formula
