Step-by-step explanation:
 
        
                    
             
        
        
        
First, we are going to find the common ratio of our geometric sequence using the formula: 

. For our sequence, we can infer that 

 and 

. So lets replace those values in our formula:


Now that we have the common ratio, lets find the  explicit formula of our sequence. To do that we are going to use the formula: 

. We know that 

; we also know for our previous calculation that 

. So lets replace those values in our formula:

Finally, to find the 9th therm in our sequence, we just need to replace 

 with 9 in our explicit formula:



We can conclude that the 9th term in our geometric sequence is <span>
