Rules of GP:
1)You will have Common ratio ,denoted with "r"
2)First term is denoted with "a"
3)Nth term is given by =a*power(r,n-1);//which is equal to a*(r power n-1);
4)Sum of the series is =a(|1-(r power n)|)/(|1-r|)
Rules of HP:
1)You can here find out common difference (d);
2)Series which are having by format.
3)nth term =1/(a+(n-1)d)
4)sum=2/(n(a+d))
