Answer:
see below
Step-by-step explanation:
-33, -27, -21, -15,....
-33 +6 = -27  
-27+6 = -21 
-21+6 = -15
This is an arithmetic sequence
The common difference is +6
explicit formula
an=a1+(n-1)d  where n is the term number and d is the common difference
an = -33 + ( n-1) 6
an = -33 +6n -6
an = -39+6n
recursive formula
an+1 = an +6
10th term 
n =10
a10  = -39+6*10
       = -39+60
       =21
sum formula

The sum will diverge since we are adding infinite numbers

Answer:
40% (option C)
Step-by-step explanation:
To find the answer, divide the number of events played in other towns by the total number of performances the band did. 
Applying this: 
12 / (18 + 12) = 
12 / 30 = 
2 / 5 = 
40%
The answer is C, 40%
