public static void main(String[] args) throws IOException{
BufferedReader buff =new BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter numerical value!");
String str = buff.readLine();
int x = Integer.parseInt(str);
for (long n=1; true; n = n + x) {
long sum = 0;
for (long i = 1; i < n; i++)
