Answer:
-2p² - 9pq + 6q²
Step-by-step explanation:
Add the like terms
p² + - 3p² = -2p²
-7pq + - 2pq = -9pq
-q² + 7q² = 6q²

The sequence forms a Geometric sequence as the rule to obtain the value for the next term is by ratio
Term 1: 1000
Term 2: 200
Term 3: 40
From term 1 to term 2, there's a decrease by 

From term 2 to term 3, there's a decrease also by 

The rule to find the 

 term in a sequence is 

, where 

 is the first term in the sequence and 

 is the ratio
So, the formula for the sequence in question is

 term = 

The sequence is a divergent one. We can always find the value of the next term by dividing the previous term by 5 and if we do that, the value of the next term will get closer to 'zero' but never actually equal to zero.
We can find a partial sum of the sequence using the formula

 for -1<r<1 
Substituting 

 and 

 we have 

 = 

 = 1250
Hence, the correct option is option number 1
 
        
        
        
T,A,Y are 40 and 2T,X,B,Z are 80
