Outputs the Fibonacci sequence between two numbers

Substituting 2008 into the general formula (1 5)* and then calculating So the answer is 3!

A sequence of number is a function that defines a domain with a set of positive integers.

Each number in the sequence is called the term of the sequence, the number in the first place is called the first term of the sequence, the number in the second place is called the second term of the sequence, and so on, the number in the nth position is called the nth term of the sequence, which is usually denoted by an. Famous sequences include Fibonacci sequences, trigonometric functions, Cattelan numbers, Yang Hui triangles, etc.

Studying math problems on the beach, they draw dots or use pebbles to represent numbers on the beach. For example, they studied that since these numbers can be represented by a triangular lattice of dots like the one shown on the right, they called them triangular numbers.

The number of squares is similarly referred to as the number of squares because these numbers are able to be represented as squares. Therefore, the number of a column in a certain order is called a number sequence.

There is a cycle for the remainder of each term in this series divided by 8.

This period is 12

2008 divided by 12 to get the remainder is 4

So the answer is 3!

For the rabbit problem, let the number series satisfy a1=1, a2=1, an=a(n-1)+a(n-2) as the Fina Pooch sequence.

Fibonacci sequence 、...

There is a cycle for the remainder of each term in this series divided by 8.

1,Not blind 1,2,3,5,0,5,5,,2,7,1,0,1,1....

This period is 12

2008 divided by 12 to get the remainder is 4

Because of the game, the answer is 3!

n=1,2,3……）

Although all the ans in this general formula are positive integers, they are represented by some irrational numbers.

The formula for the general term of this series of numbers can be found by the eigenroot method.

The Fibonacci sequence refers to such a sequence of numbers 、...This sequence starts with the third term, each of which is equal to the sum of the first two terms. Its general formula is:

1 5)* (also known as the "bine's formula", is an example of using irrational numbers to represent rational numbers. (5 for root number 5) Interestingly, such a series of numbers that are completely natural numbers is actually expressed in irrational numbers.

Mathematically, the Fibonacci sequence is defined in a recursive way:

f0 = 0

f1 = 1

fn = fn - 1 + fn - 2 In literal terms, the Fibonacci sequence starts with 0 and 1, and the Fibonacci numbers after that are added by the previous two numbers. The first few Fibonacci numbers are:

This sequence starts with the third term, each of which is equal to the sum of the first two terms.
