Find the fifth term in the geometric sequence, given the first term and
the common ratio.
a1 = 2 and r = 3
a5 = [ ?]

We can solve this in 2 ways
Since a1 = 4
a2 = 4 * (3) = 12 i.e( a1* common ratio)
a3 = 12 * (3) = 36 i.e( a2 * common ratio)
a4 = 36 * (3) = 108 i.e( a3* common ratio)
a5 = 108 * (3) = 324 i.e(a4*common ratio)

and so on

That’d be 9 years or something
