Answer:
D
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 = 8 and d = - 3 , then
= 8 - 3(n - 1) = 8 - 3n + 3 = - 3n + 11 → D
Wouldn’t the answer be 8 and 3
Let the number of CD's be x and total cost be y
