##Number Series with a Twist 2
##Link to this Question
##
##Consider the following series: 1, 1, 2, 3, 4, 9, 8, 27, 16, 81, 32, 243, 64, 729, 128, 2187 …
##
##This series is a mixture of 2 series – all the odd terms in this series form a geometric series and all the even terms form yet another geometric series. Write a program to find the Nth term in the series.
##
##The value N in a positive integer that should be read from STDIN. The Nth term that is calculated by the program should be written to STDOUT. Other than value of n th term,no other character / string or message should be written to STDOUT. For example , if N=16, the 16th term in the series is 2187, so only value 2187 should be printed to STDOUT.
##
##You can assume that N will not exceed 30.




n = int(input("enter Number "))

a=1
b=1

for i in range(1,n+1):
    if (i%2) != 0:
        a = a*2
    else:
        b = b*3

if (n%2) != 0:
    print("{} term of the series is {}".format(n,a/2))
else:
    print("{} term of the series is {}".format(n,b/3))
