Java Program: Sum of Powers Series
30 (i). Write a program in Java to find the sum of the given series:
x1 + x2 + x3 + x4 + ..... + xn
Program Title: Sum of Powers Series
import java.util.Scanner;
public class SumOfPowersSeries {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.print("Enter the value of x: ");
double x = sc.nextDouble();
System.out.print("Enter the number of terms (n): ");
int n = sc.nextInt();
double sum = 0.0;
for (int i = 1; i <= n; i++) {
sum += Math.pow(x, i);
}
System.out.println("Sum of the series is: " + sum);
sc.close();
}
}
Output
Sample Input / Output Enter the value of x: 2 Enter the number of terms (n): 5 Sum of the series is: 62.0
📝 Explanation
21 + 22 + 23 + 24 + 25 = 2 + 4 + 8 + 16 + 32 = 62
