S = a + a² + a³ + .................... + aⁿ

Answer 1

import java.util.*;
public class Q3a
{public static void main(String args[])
{int a, n; 
double term, sum = 0;
Scanner obj = new Scanner(System.in);
System.out.println("Enter the value of a");
a = obj.nextInt();
System.out.printin("Enter the value of n");
n = obj.nextInt();
for (int i = 1; i <= n; i++)
{
term = Math.pow(a, i);
System.out.printIn(term); // optional print
sum = sum + term;
}
Systern.out.println("Sum of the series = " +sum);
}}
