100 points! a water tank is being drained. the table shows the number of gallons, g, of water left in the tank after h hours. the drainage rate will remain the same. table: h(hours); 1,2,3,4. g(gallons) ; 384,288,216,162. part a: what type of sequence can be used to model the number of gallons remaining? explain your answer. part b: write the recursive formula to express gh, the number of gallons left in the tank after h hours, in terms of the number of gallons left in the tank the previous hour, gh-1. part c: write the explicit formula to express gh, the number of gallons left in the tank after h hours. part d: use your explicit formula from part c to find the number of gallons of water left after 12 hours. show all your work, round your answer to the nearest gallon. part e: convert your final answer from part d into quarts, show all work. k
