        System.out.print("Enter n: ");
        int n = in.nextInt();
        
        double sum = 0;
        int a = 1;
        for (int i = 1, j = 1; i <= n; i++, j+=2) {
            double term = Math.pow(x, i) / j * a;
            sum += term;
            a *= -1;
        }
        System.out.println("Sum = " + sum);
    }
}
