Given a number of terms and a number ‘x’ the task is to calculate the value upto ‘n’ terms of the below given series.
Series: (x/a)2 + (x/a)3 + (x/a)4 + (x/a)5 + (x/a)6 …………… + ‘n’ terms.
Note: Value of ‘x’ and ‘a’ is to be given by user.
Java
import java.util.*;
public class Series
{
public static void main(String args[])
{
int n=0,x=0,a=0;
double result=0.0;
Scanner sc=new Scanner(System.in);
System.out.print("Enter a number: ");
x=sc.nextInt();
System.out.print("Enter a number: ");
a=sc.nextInt();
System.out.print("Enter number of terms: ");
n=sc.nextInt();
for(int i=1;i<=n;i++)
{
result=result+Math.pow(((double)x/a),i+1);
}
System.out.println("Result of the series: "+result);
}
}
