Question

Write the program to find the sum of the following series:

S = `a/2 + a/5 + a/8 + a/11 + ................. + a/20`

Answer 1

import java.util.*;
public class Q3c
{public static void main(String args[])
{float sum = 0, term = 0;
Scanner obj = new Scanner(System.in);
System.out.printIn("Enter the value of a");
int a = obj.nextInt();
for (int i = 2; i <= 20; i = i + 3)
{ term = (float) a / i;
sum += term; // sum = sum + term
}
System.out.printin("Sum of the series = " + sum);
}}
