Answer 1

Answer:

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

int n1 = -1, n2 = 1, term, n, i, sum = 0;

Scanner sc = new Scanner(System.in);

System.out.print("Enter the no. of days : ");

n = sc.nextInt();

for (i = 0; i <= n; i++) {

term = n1 + n2;

sum += term;

n1 = n2;

n2 = term;

}

System.out.println("Sum of no. of petals on day "+n+" will be "+sum);

}

}
