So,

We can see that the sum of -7 and 7 is zero.
Hence,
The correct answer is: -7, 7
 
        
                    
             
        
        
        
It is geometric because it is increasing by a common factor. If you multiply the previous number by 6 you receive the next number. If it were arithmetic you would add the number, not multiply.
