Question

A java program that calls a function called findA_n(int n, int a_0). The first parameter should be the index in the sequence, and the second parameter should be in the initial condition. Your main() routine should return the result of findA_n() to the console widnow, and findA_n should be called 3 times as follows: findA_n(5, 2); findA_n(5, 3); findA_n(5, 4); The formula for a_n should be a_n = -3 a_{n-1} + 12. The output should be the 6th element of the sequence, a_{5}, where the initial element is 2, 3, and 4, respectively. Your function must implement recursion

Explanation / Answer

class TestClass {
    static int findA_n(int n, int a_0) {
        if (n = 0)
            return a_0;
        return -3 * findA_n(n-1, a_0) + 12;
    }
    public static void main(String[] args) {
        System.out.println(finrA_n(5));
    }
}
