Answer:
C
Step-by-step explanation:
You just find the rate of change. So you would divide 30/1 which equals 30. So the equation is y=30x.
 
        
                    
             
        
        
        
Notice that if you go forward, the common ratio is 5.  Each new term is found by mult. the previous term by 5.
If, on the other hand, you go backwards (terms decreasing), then you divide a term to find what the previous term was.
Here, divide 1 by 5 to find the first term.  It's 1/5.
