Answer:
addition
Step-by-step explanation:
18 (<u> d </u> - 9 ) = 198
      3
divide both side by 18
<u> d </u> - 9 = <u> 198 </u>  
 3             18
<u> d </u> - 9 = 11 
 3 
multiply both sides by 3
d - 27 = 33
add 27 to both sides
d = 33 + 27
lastly, add them together
d = 60
therefore, the last step is addition
 
        
             
        
        
        
Answer:
M= 0
Step-by-step explanation:
the ys are the same
 
        
             
        
        
        
Given the recursive formula, each terms is five time the previous one.
This means that:
 is 5 times 
, which means 
- in turn, 
 is 5 times 
, so we have 
. This means that 
 - Finally, 
 So, substituting this back gives 

In general, since you have 
, each time you compute a new term you multiply by a factor of 5, so if 
, you have
