        //Now define a  method named series
        static void series ( int a, int n)
        {
            int first_num = a;
            int while_condition = n;
            //print the first num
            System.out.print("\n" + first_num + ", ");
            //define a loop
            while (while_condition != 0) {
                if (while_condition % 2 == 0) {
                    for (int i = 0; i < 2; i++) {
                        first_num = (first_num * first_num) + (while_condition - 1);
                        if (while_condition != 0) {
                            System.out.print(first_num + ", ");
                        }

                    }
                    //update while_condition
                    while_condition = while_condition - 1;
                } else {
                    for (int i = 0; i < 2; i++) {
                        first_num = (first_num * first_num) - (while_condition - 1);
                        if (while_condition != 0) {
                            System.out.print(first_num + ", ");
                        }

                    }
                    //update while_condition
                    while_condition = while_condition - 1;
                }
            }
            System.out.println("\n");
        }

    public static void main(String[] args) {

        //declare the given two variables a and n and initialiaze them
        int a = -2;
        int n = 4;
        series(a,n);
    }
