Geometric sequences is a sequence of numbers where each term after the first is found by multiplicatying the previous by a common ratio, and is given by the expression:

an= the term we want to find
a1= the first term of the sequence
n= the position of the term
r= ratio is the cocient between two consecutive pairs
r=6/3=2
r=12/6=2
So, the 50th term would be:
