Answer:
36th term
Step-by-step explanation:
The nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 9 and d = - 4 - (- 9) = - 4 + 9 = 5 , then
= - 9 + 5(n - 1) = - 9 + 5n - 5 = 5n - 14
Equate the nth term to 166 and solve for n
5n - 14 = 166 ( add 14 to both sides )
5n = 180 ( divide both sides by 5 )
n = 36
