Answer:
Step-by-step explanation:
Given :
Expression :
Put n = 1
Put n = 2
Put n = 3
Continuing in this manner we will get the geometric sequence :
243,729,2187,6561 ........
Formula for nth term of G.P. :
a= 243
r = common ratio between the consecutive terms .
Substituting values in the formula :
Hence the general term of the sequence is
A
since 36=6² and the other option is not square of integer
