Answer:
 The series is equal to 1364
Explanation:
 You have a series there ... 
 A series is the sum of a series of values 
 If it starts at n = 1 and ends at n = 5 then it substitutes the values and adds: 
 
 4 ^ 1 + 4 ^ 2 + 4 ^ 3 + 4 ^ 4 + 4 ^ 5 
 = 4 + 16 + 64 + 256 + 1024 
 = 1364 
 Finally the series is equal to 1364
