Question

Write a program in Java to calculate and print average of the first ten terms of Fibonacci series using for loop

Answer 1

public class Fibonacci {

public static void main(String[] args) {

 int a = -1, b = 1, c = 0;

 float sum = 0.0f;

 for(int i = 0; i < 10; i++){

  a = b;

  b = c;

  c = a + b;

  sum += c;

 }

 System.out.println("Average of first ten terms of Fibonacci series : " + (sum/10));

}

}

Answer 2

class Main

{

public static void main(String args[])

{

int first_num = 0;

int second_num = 1;

int i = 0;

double avg = 0;

for(i=1; i<=5; i++) //Taken 5 Because it prints two fibonacci numbers at once

{

System.out.println(first_num +"\t");

System.out.println(second_num);

avg = (first_num+second_num)/10.0;

first_num = first_num+second_num;

second_num = first_num+second_num;

}

System.out.print("\nAverge is "+avg);

}}
