A recursive rule for a geometric sequence is 
       
      
                
     
    
    
    
    1  answer:
            
              
Answer: 
C. 
Step-by-step explanation: 
Iterative geometric sequence:
Recursive geometric sequence:
The equations are very similar and you only really need to rearrange it. The factor (2/3) and the first term (9) are given, so you can write the iterative equation:
And so the answer is C.

-20 -18 -6 -4 2 4 this is the answer
        
                    
             
        
        
        
That would be choice 2. One acute angle is the complement of the other 
eg in a 90-60-30 triangle sine 30 = cos 60
 
        
                    
             
        
        
        
Circumference = PI x Diameter
        
             
        
        
        
X/3 - 38 = 42
        
             
        
        
        
 Answer: 
92
Step-by-step explanation: 
20% of 460 is 92 so it would be 92
