**Fibonacci Sequence:**

**Fibonacci recursion python: **The Fibonacci Sequence is a series of integers named after the Italian mathematician Fibonacci. It is merely a string of numbers that begins with 0 and 1 and is then followed by the addition of the two numbers before it.

**Recursion:**

**Python fibonacci recursive: **If you’re familiar with Python functions, you’ll know that it’s typical for one function to call another. It is also feasible for a function in Python to call itself! A recursive function calls itself, and the process of using a recursive function is known as recursion.

Although it may appear strange for a function to call itself, many sorts of programming challenges are better stated recursively.

Given a number, the task is to find the Fibonacci sequence till the given number using recursion.

**Examples:**

**Example1:**

**Input:**

given number = 23

**Output:**

The Fibonacci Sequence till the given number 23 = Number = 0 Number = 1 Number = 1 Number = 2 Number = 3 Number = 5 Number = 8 Number = 13 Number = 21 Number = 34 Number = 55 Number = 89 Number = 144 Number = 233 Number = 377 Number = 610 Number = 987 Number = 1597 Number = 2584 Number = 4181 Number = 6765 Number = 10946 Number = 17711

**Example2:**

**Input:**

given number =13

**Output:**

Enter some random number = 13 The Fibonacci Sequence till the given number 13 = Number = 0 Number = 1 Number = 1 Number = 2 Number = 3 Number = 5 Number = 8 Number = 13 Number = 21 Number = 34 Number = 55 Number = 89 Number = 144

## Program to Find the Fibonacci Series Using Recursion

**Fibonacci series using recursion in java: **Below are the ways to find the Fibonacci Series using the recursive approach in Python:

### 1)Using Recursion(Static Input)

**Approach:**

- The user must give the number as static input and store it in a variable.
- Pass the given number as a parameter to the Fibonacci recursive function.
- The base condition is defined as a value that is less than or equal to 1.
- Otherwise, call the function recursively with the argument as the number minus 1 plus the function that was called recursively with the parameter as the number minus 2.
- Use a for loop to return the Fibonacci sequence and return the result and print the result.
- The exit of the program.

**Below is the implementation:**

# function which finds the fibonacci sequence recursively def fibonacciRecursion(numb): # The base condition is defined as a value that is less than or equal to 1. if(numb <= 1): return numb else: # Otherwise, call the function recursively with the argument as the number minus 1 plus the function that was called # recursively with the parameter as the number minus 2. return(fibonacciRecursion(numb-1) + fibonacciRecursion(numb-2)) # The user must give the number as static input and store it in a variable. numb = 23 print("The Fibonacci Sequence till the given number", numb, ' = ') # Looping from 1 to given number using for loop for n in range(numb): # passing the iterter value as argument to the recursive function fibonacciRecursion print('Number = ', fibonacciRecursion(n))

**Output:**

The Fibonacci Sequence till the given number 23 = Number = 0 Number = 1 Number = 1 Number = 2 Number = 3 Number = 5 Number = 8 Number = 13 Number = 21 Number = 34 Number = 55 Number = 89 Number = 144 Number = 233 Number = 377 Number = 610 Number = 987 Number = 1597 Number = 2584 Number = 4181 Number = 6765 Number = 10946 Number = 17711

In this way, we can print the Fibonacci sequence of the given number using recursion.

### 2)Using Recursion(User Input)

**Approach:**

- The user must give the number as user input using the int(input()) function and store it in a variable.
- Pass the given number as a parameter to the Fibonacci recursive function.
- The base condition is defined as a value that is less than or equal to 1.
- Otherwise, call the function recursively with the argument as the number minus 1 plus the function that was called recursively with the parameter as the number minus 2.
- Use a for loop to return the Fibonacci sequence and return the result and print the result.
- The exit of the program.

**Below is the implementation of the above approach:**

# function which finds the fibonacci sequence recursively def fibonacciRecursion(numb): # The base condition is defined as a value that is less than or equal to 1. if(numb <= 1): return numb else: # Otherwise, call the function recursively with the argument as the number minus 1 plus the function that was called # recursively with the parameter as the number minus 2. return(fibonacciRecursion(numb-1) + fibonacciRecursion(numb-2)) # The user must give the number as user input using the # int(input()) function and store it in a variable. numb = int(input('Enter some random number = ')) print("The Fibonacci Sequence till the given number", numb, ' = ') # Looping from 1 to given number using for loop for n in range(numb): # passing the iterter value as argument to the recursive function fibonacciRecursion print('Number = ',fibonacciRecursion(n))

**Output:**

Enter some random number = 13 The Fibonacci Sequence till the given number 13 = Number = 0 Number = 1 Number = 1 Number = 2 Number = 3 Number = 5 Number = 8 Number = 13 Number = 21 Number = 34 Number = 55 Number = 89 Number = 144

**Explanation:**

- The number of terms must be entered by the user and saved in a variable.
- A recursive function takes the number as a parameter.
- The number must be less than or equal to one as a starting point.
- Otherwise, the function is run recursively with the number minus 1 as an input, which is added to the function that is called recursively with the number minus 2.
- The result is returned, and the Fibonacci sequence is printed using a for statement.
- In this way, we can print the Fibonacci sequence of the given number using recursion.
