Given : Geometric Sequence is 1 , 3 , 9 , 27 . . . .
The First Term of the Geometric Sequence is a₁
⇒ a₁ = 1
Common Ratio of a Geometric Sequence is the Ration of Second term to its First term
⇒ Common Ratio of Given Geometric Sequence = 3
Recursive Rule :
[tex]\mathsf{\implies a_n = (3)a_n_-_1}[/tex]
