First 18 terms of the sequence are: 1,1,2,3,5,8,13,21,34,55,89,144,233,377,610,987,1597, 2584. Every third term is 2,8,34,144,610,2584. These are all even so the largest number is likely 2.
The two number before a number are added to get the next number. So if the first numbers are 0,1,1,2,3,5, and 8 for example. You add 0+1=1 which is the third number. 1+1=2 which is the 4th number in the sequence etc. Of course, you can do this forever so the sequence is infinite. In symbols we write the sum as Fn =Fn-1 +Fn-2 The n refers to the nth number in the sequence. For example if n=4, than Fn =2
The Fibonacci sequence is defined as follows:f(1) = 1,f(2) = 1 andf(n) = f(n-1) + f(n-2) for all n >2.The first two are the "seeds" and the third is the recursive formula which states that each term, after the second, is the sum of the two preceding terms.
n means any number in the sequence.Let's take for example the sequence; x=0,2,4,6,8,10,12,14when x=4, then n=3, because 4 is the third number in the sequence

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.
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.
21 It is the Fibonacci secuence.1+1=2 1+2=3 2+3=5 and so on... 1,1,2,3,5,8,13,21,34,55,89,144,233,377,610...

The Fibonacci series is a recursively defined sequence of numbers:x1 = x2 = 1xn = xn-1 + xn-2In words: The first two Fibonacci numbers are 1, and each following number is the sum of the two predessors.1, 1, 2, 3, 5, 8, 13, 21, ...Note:There is another definition of the Fibonacci series:x0 = 0x1 = 1xn = xn-1 + xn-2In this case, the sequence begins with 0:0, 1, 1, 2, 3, 5, 8, 13, 21, ...The Fibonacci series is a sequence of numbers, starting with 0 and 1, where each number, starting with the third number, is the sum of the preceding two numbers. The first 11 numbers in this series is 0 1 1 2 3 5 8 13 21 34 55. The ratio of two sequential Fibonacci numbers, as the series approaches infinity, approaches the golden mean, or phi, which has interesting mathematical and other implications.
The Fibonacci sequence is defined as follows:f(1) = 1,f(2) = 1 andf(n) = f(n-1) + f(n-2) for all n >2.The first two are the "seeds" and the third is the recursive formula which states that each term, after the second, is the sum of the two preceding terms.
The third number is 2 -- the first number is 1, second is 1, next is 1+1=2, then 1+2=3, 2+5=5 etc.
The Fibonacci sequence is a series of sums of two counting numbers and it starts with the lowest two, namely 0 and 1. Each successive number in the sequence is the sum of the two preceding it. Like this: The first term is usually 0 (although sometimes it is left out). The second term is 1. The third term is 1 + 0 = 1. The fourth term is 1 + 1 = 2. The fifth term is 1 + 2 = 3. The sixth term is 2 + 3 = 5. So the first 15 terms in the sequence would be: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, ... More formally, the Fibonacci sequence is defined recursively as: a1 = 0 a2 = 1 an+1 = an-1 + an There is also a general formula for the nth Fibonacci number: ( [1+sqrt(5)]n - [1-sqrt(5)]n ) / (2n * sqrt(5)) (where sqrt() means square root of)
n means any number in the sequence.Let's take for example the sequence; x=0,2,4,6,8,10,12,14when x=4, then n=3, because 4 is the third number in the sequence
The missing number in this sequence is 64, or 4 raised to the third power. You find the answer by noting that each number in the sequence is a counting number starting at 1 that is raised to the third power. For example, 2 raised to the third power (2 x 2 x 2) is 8.
