A Fibonacci number, Fibonacci sequence or Fibonacci series are a mathematical term which follow a integer sequence. The first two numbers in Fibonacci sequence start with a 0 and 1 and each subsequent number is the sum of the previous two.

According to the link, zero is the first number in the series.

I think it was rabbits.

the Fibonacci sequence was first published by Leonardo Fibonacci in his book "Liber Abaci" in 1202.

Since zero is both a positive number (defined as such), and not part of the Fibonacci sequence, then the first positive non-Fibonacci number is zero (0). If zero does not fit in you definition of positive number, then the answer would be four (4).

If the Fibonacci sequence is denoted by F(n), where n is the first term in the sequence then the following equation obtains for n = 0.

A recursive sequence uses previous numbers to find the next number in a sequence after the base case. The Fibonacci sequence is an example of such a sequence. The base numbers of the Fibonacci sequence are 0 and 1. After that base, you find the next number in the sequence by adding the two previous numbers. So, the Fibonacci sequence looks like so: 0, 1, 1, 2, 3, 5, 8.... So, the third number is found by adding the first and second numbers, 0 and 1. So the third number is 1. The fourth number is found by adding the second and third numbers, 1 and 1. So, the fourth number is 2. You can continue on this way forever.

Leonardo Fibonacci first recorded his sequence in his book Liber Abaci, which was published in 1202.

the first seven Fibonacci numbers are 1,1,2,3,5,8,13. 13 is a Fibonacci number.

If you start with 1, the common factors are 1 and 3. If you start with zero, as Fibonacci did, the common factor is 1.

Answer 144 which is F(12) Reason 55 and 89 are the 10th and 11th Fibonacci numbers, If we add these we have 144 which is the 12 Fibonacci number and is a perfect square. I am using F(0) as the 0 Fibonacci number and F(1) as the first.

Assume the question refers to the standard Fibonacci sequence where the first two numbers are 0 and 1.The sequence progresses :- 0, 1, 1, 2, 3, 5, 8, 13, 21, 34 - which is the number required.

The Fibonacci sequence is not something that can be "solved"; he merely recognised the assortment of numbers as being the first few members of that sequence.

They will always follow some Fibonacci sequence. If P and Q are any two numbers, then they belong to the Fibonacci sequence with the first two numbers as P and (Q-P).

The Fibonacci sequence, was first known by the ancient people of India. When Fibonacci travelled there in the 1200's he learnt it from them and then passed on his learning to the rest of Europe through his book, Liber Abaci.

20 of them.

In a Fibonacci sequence, sum of two successive terms gives the third term.... here is the Fibonacci sequence: 0,1,1,2,3,5,8,13,21,34,55,89,144........ General formula to generate a Fibonacci sequence is """Fn= Fn-1 + Fn-2""" To check whether a number is Fibonacci or not follow the following steps: 1) Get the number as input from user. 2) Fix the first two numbers of sequence as 0 and 1. 3) put a sentinel loop with upper limit being the input number. 4)in the body of loop generate the next number in sequence in each iteration and continue swapping the values as follows: a=0 b=1 next=a+b while (next< input) a=b b=next next=a+b wend 5) lastly when program exits the loop compare the last number of sequence with the input number if they are equal then number is Fibonacci otherwise not. otherwise the last term of sequence will be less than the input number.

The first Fibonacci number greater than 23 is 34.

Those are the first six terms of the Fibonacci series.

0,1,1,2,3,5,8,13

No. For example: 4181 / 37 = 113 so it can't be prime. But 4181 is the first composite number in the Fibonacci sequence with a prime index. ;)
