Answer 1

Java program to display sum of series : 1/2 + 1/3 + 1/5 + 1/7........1/29

Step-by-step explanation:

Java Program

public class Main {  

   static boolean check_Prime(int number)  

   {  

       if(number== 1) {  

           return false;  

   }  

       for (int i = 2; i*i <= number; i++) {  

           if (number% i == 0) {  

               return false;  

           }  

       }  

       return true;  

   }  

   static double psum(int l, int r)  

   {  

       double sum = 0;  

       for (int i = r; i >= l; i--) {  

           boolean is_prime = check_Prime(i);  

           if (is_prime) {  

               sum = sum + 1.0/(double)i;  

           }  

       }  

       return sum;  

   }

   public static void main(String[] args)  

   {  

       int start = 2, end = 29;  

       double sumOfseries =psum(start, end);

       System.out.println("sum of series : "+sumOfseries);  

   }  

}

Output

sum of series : 1.533438771872032
