Step-by-step explanation:
Below average rainfall in a region for several months
Not enough rain to be absorbed into the ground before evaporating
Cutting down trees and overuse of land
Hot dry air masses blown into a region by westerly winds
Human activities that deplete the water table faster than it can be replaced
 
        
                    
             
        
        
        
The explicit formula of the sequence is given by a_n = -4n(n-1).
We have to find the first five terms of the sequence.
The first term:

The second term:

The third sum:

The fourth term:

The fifth term:

Thus, option D is correct.
