Answer:
the answer is 9
Step-by-step explanation:
 
        
                    
             
        
        
        
Ok so
Q.1=B
Q.2=B
Q.3(a)=(d-45)+m+65
      (b)=d+m+20  
        
             
        
        
        
You will save $15
x×0.15=5
x=33.33333
x×0.45=15
        
             
        
        
        
Answer:
The required recursive formula is:

Step-by-step explanation:
We are given a geometric sequence as:
6,-18,54,-162,.....
Clearly after looking at different terms of the sequence we could observe that the sequence is an geometric progression (G.P.) with common ratio= -3 denoted by r.
Let  represents the nth term of the sequence.
 represents the nth term of the sequence.
This means that:

As the common ratio is -3.
so,

Hence, the required recursive formula for the geometric sequence is:
