Answer 1

Explanation:

Examples:

Input: a = 3, n = 3

Output: 0.6666667

The series is 1/3 + 1/9 + 1/27 which is

equal to 0.6666667

Input: a = 5, n = 4

Output: 0.31039998

Answer 2

The longitudinal gap between Arunachal Pradesh and Gujarat is about 30°. Due to this, there is time lag of about two hours between these states. ... The Indian Standard Time is taken from the time of Standard Meridian of India and hence, the watches show the same time in both the states.
