Answer: 
Step-by-step explanation:
 You know that the formula to find the sum of a finite geometric series is:
 
 Where  is the number of terms,
 is the number of terms,  is the first term and
 is the first term and  is the common ratio (
 is the common ratio ( ).
).
 The steps to find the sum of the first 12 terms of the given geometric serie, are:
 1. Find the common ratio "r". By definition:
 
 Then:
 
 2. Finally, knowing that:
 
 You must substitute values into the formula. 
 Then you get:
