Question

Write a program to find the sum of 1st 10 numbers of Fibonacci series i.e. 1,1,2,3,5,8,13….
Fibonacci series is such a series which starting from 1 and 1, and subsequent numbers are the
sum of the previous two numbers.

Answer 1

Required Answer:-

Question:

• Write a program to find the sum of 1st ten numbers of Fibonacci Series.

Solution:

This is an easy question. Read this post to get your answer.

Here is the program. This is written in Java.

public class FibonacciSum {

public static void main(String[] args) {

int a=1, b=0, c=1, sum=0;

for(int i=1;i<=10;i++) {

c=a+b;

a=b;

b=c;

sum+=c;

}

System.out.println("Sum is: "+sum);

}

}

★ We need to find each term of the Fibonacci series and add them up. We will store the sum in a variable and display it. Each term of the Fibonacci series is the sum of previous two terms.

Output is attached.

Answer 2

Question:

Write a program to find the sum of 1st 10 numbers of Fibonacci series, i.e. 1,1,2,3,5,8,13…. Fibonacci series is such a series which starting from 1 and 1, and subsequent numbers are the sum of the previous two numbers.

Solution:

Language used: Java

public class FibSum

{

static void main()

{

int i,a=1,b=0,c;

System.out.println("Fibonacci series =");

for(i=1;i<=10;i++)

{

c=a+b;

System.out.print(c+" ");

a=b;

b=c;

}

}
