Answer 1

Answer:

import java.util.*;

public class Program

{

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

System.out.println("Enter the value for A ");

double input = sc.nextFloat();

double sum=0;

for(int i=2;i<=20;i+=3) // to divide by 2,5,8 so on that is why increase by 3 to i

{

sum+=input/i;

}

System.out.println(sum );

}

}

def series(a):

_sum = 0

for i in range(2, 21, 3):

_sum += a / i

return _sum

print("result:", series((a := int(input("a: ")))))
