Where is the first term in the sequence, and r is the common ratio and
is the nth term of the sequence:
In this case we have the following sequence
Then:
The recursive formula for the geometric sequence has the following formula

Step-by-step explanation:
Given:
Total number of CDs = 6
Cost price (including tax) = $71.40
Each CD had a tax of $1.10
To find the price of each CD before tax Let's first find the price of each CD after tax.
Price after tax =
Price of each CD after tax = $11.90
Since each CD had a tax of $1.10, price of each CD before tax would be : $11.90 - $1.10 = $10.80
Therefore price of each CD before tax is $10.80
