All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3,5, 8, 13. Complete the fibonacci() method, which takes in an index, n, and returns the nth value in the sequence. Any negative index valuesshould return -1.Ex: If the input is:7the output is:fibonacci (7) is 13Note: Use recursion and DO NOT use any loops.318446.2220060.qx3zay7LAB8.19.1: LAB: Fibonacci sequence (recursion)0/ 10ACTIVITYLabProgram.javaLoad default template.import java.util.Scanner;public class LabProgram {public static int fibonacci (int n) {/* Type your code here. */}public static void main (String[] args) {Scanner scnr = new Scanner (System.in);int startNum;startNum = scnr.nextInt () ;System.out.println ("fibonacci (" + startNum + ") is}+ fibonacci (startNum));

1. The sorted values array contains 16 integers 5, 7, 10, 13, 13, 20, 21, 25, 30,32, 40, 45, 50, 52, 57, 60. Indicate the sequence of recursive calls that are made tobinaraySearch, given an initial invocation of binarySearch(32, 0, 15).show only the recursive calls. For example, initial invocation is binarySearch(45,0,15)where the target is 45, first is 0 and last is 15.
