no excuse no spam no improper answer!!!!

Answer 1

/*We can write the program by using java or c or c++ but java is more advanced so we should use java here and about of utility version*/

import java.util.*;

public class Scanner

{

public static void main(String args[])

{

//since there is need of input so using scanner class

Scanner in=new Scanner(System.in);

int s=0, m=10,n, i;

//declairing the value of n

n= in.nextInt();

//Since the program is terminating one so, using for loop to shorten it

for(i=5;i<=n;i=i+5)

{

//mathematical expression

s=Math.pow(i,2)-m+s;

//Displaying the output

System.out.println("The sum of the series is"+s);

}

}

}
