Hint -

1 - Use for loop and start iteration from 1 to userinput

2 - get square of each iteration value

3 - get sum of each square value.

Answer 3

class Series
{
public static void main(String args)
{
int n = Integer.parseInt(args[0]);
int s=0;
for(int i=1;i<=n;i++)
{
System.out.println(i + “ * “ + i + “ = “ + i*i);
s+= (i*i);
}
System.out.println(“The summation of the series : “ + s);
}
}
