Hi Hariharan,

Can you try the below code. You can call the method as below.
  
SeriesSum.sumofseries(10,2);


  
public class SeriesSum {
    public static void sumofseries(Integer n, Integer x){
       Integer sum=0;
        for(Integer i = 1 ; i<=n ;i++){
   {
   sum= sum+i;
   }
    
}       
        Integer totalvalue= x*sum;
        system.debug('answer is '+totalvalue);
       
    }

}

The logic is simple 1x+2x+3x+4x+... nx= x(1+2+3+4+5+..n)


Let me know if you face any issues.
