Arithmetic sequence

Print Arithmetic Sequence by for-loop

public class ArithmeticSequenceExample {
    static void arithmeticProgression(int val, int ratio, int n) {
        for (int i = 1; i <= n; i++) {
            System.out.print((val + (i - 1) * ratio) + " ");
        }
    }

    public static void main(String[] args) {
        int val = 1;
        int ratio = 2;
        int n = 10;

        arithmeticProgression(val, ratio, n);
    }
}

Output

1 3 5 7 9 11 13 15 17 19

Print Arithmetic Sequence by Recursion

public class ArithmeticSequenceExample {
    static void arithmeticProgression(int ratio, int n, int val) {
        System.out.print(val + " ");
    
        if (n == 0)
            return;
    
        arithmeticProgression(ratio, n - 1, val + ratio);
    }

    public static void main(String[] args) {
        int val = 1;
        int ratio = 2;
        int n = 10;

        arithmeticProgression(ratio, n - 1, val);
    }
}

Output

1 3 5 7 9 11 13 15 17 19
