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
