The sum of the terms of a geometric sequence with common ratio lesser than 1 is calculated through the equation,
Sn = (a1) x (1 - r^n) / (1 - r)
Substituting the known values,
S5 = (6) x (1 - (1/3)^5) / (1 - 1/3) = 242/27
Thus, the sum of the first five terms is approximately equal to 8.96.
24a-18a+12a is equal to 18a
hence, divide it by 6a
so you get 3a :)

Answer:
14
Step-by-step explanation:
First, find the percentage of the other types of music.
Since 30 + 50 = 80, the other 20% will be other music.
To find 20% of 70, multiply 70 by 0.2:
70(0.2)
= 14
So, there are 14 CDs that are other types of music.
