What is an Geometric Progression(AP)?

GP is a type of sequence where each succeeding term is produced by multiplying each preceding term by a fixed number .

Constituting an GP according to the question

36,864 , 18432 , 9216 , ...........

In order to find nth term  of an GP, formula used will be :

a(n) = a (r^(n-1))

considering above GP ,

a(n) = ? water left after 11 days

a = 36864

r= 18432 /36864 = 1/2

n = 11

a(n) = 36864 ((1/2)^(11-1))

  a(n) =   36

Hence 36 L of water will be left after 11 days
