## Program to Print Series 1 2 5 8 15 28 51 94….N in Python

Below are the ways to print the series** (1 2 5 8 15 28 51 94….N)** till the given number N in Python:

### Method #1: Using While Loop (Static Input)

**Approach:**

- Give the number N (Limit) as static input and store it in a variable.
- Take a variable to say
**itr**and initialize its value to 4. - Check if the given number is greater than or equal to 1 using the if conditional statement.
- If it is true, then print 1 separated by spaces using the end function.
- Check if the given number is greater than or equal to 2 using the if conditional statement.
- If it is true, then print 2 separated by spaces using the end function.
- Check if the given number is greater than or equal to 3 using the if conditional statement.
- If it is true, then print 5 separated by spaces using the end function.
- Take another variable say
**m**and initialize its value to 1. - Take another variable say
**n**and initialize its value to 2. - Take another variable say
**o**and initialize its value to 5. - Loop until the above-declared variable itr value is less than or equal to the given number using the while loop.
- Inside the loop, add the above 3 values m, n, o and store them in a variable say
**rslt**. - Assign the value of n to m.
- Assign the value of o to n.
- Assign the value of
**rslt**to**o**. - Print the value of the
**rslt**separated by spaces using the end function. - Increment the above
**itr**value by 1. - The Exit of the Program.

**Below is the implementation:**

# Give the number N(limit) as static input and store it in a variable. gvn_numb = 13 # Take a variable to say itr and initialize its value to 4. itr = 4 print("The above series till the given number{", gvn_numb, "} is :") # Check if the given number is greater than or equal to 1 using the if conditional # statement. if gvn_numb >= 1: # If it is true, then print 1 separated by spaces using the end function. print("1 ", end="") # Check if the given number is greater than or equal to 2 using the if conditional # statement. if gvn_numb >= 2: # If it is true, then print 2 separated by spaces using the end function. print("2 ", end="") # Check if the given number is greater than or equal to 3 using the if conditional # statement. if gvn_numb >= 3: # If it is true, then print 5 separated by spaces using the end function. print("5 ", end="") # Take another variable say m and initialize its value to 1. m = 1 # Take another variable say n and initialize its value to 2. n = 2 # Take another variable say o and initialize its value to 5. o = 5 # Loop until the above-declared variable itr value is less than or equal to the # given number using the while loop. while itr <= gvn_numb: # Inside the loop, add the above 3 values m, n, o and store them in a variable # say rslt. rslt = m + n + o # Assign the value of n to m. m = n # Assign the value of o to n. n = o # Assign the value of rslt to o. o = rslt # Print the value of the rslt separated by spaces using the end function. print(rslt, end=" ") # Increment the above itr value by 1. itr += 1

**Output:**

The above series till the given number{ 13 } is : 1 2 5 8 15 28 51 94 173 318 585 1076 1979

### Method #2: Using While loop (User Input)

**Approach:**

- Give the number N (Limit) as user input using the int(input()) function and store it in a variable.
- Take a variable to say
**itr**and initialize its value to 4. - Check if the given number is greater than or equal to 1 using the if conditional statement.
- If it is true, then print 1 separated by spaces using the end function.
- Check if the given number is greater than or equal to 2 using the if conditional statement.
- If it is true, then print 2 separated by spaces using the end function.
- Check if the given number is greater than or equal to 3 using the if conditional statement.
- If it is true, then print 5 separated by spaces using the end function.
- Take another variable say
**m**and initialize its value to 1. - Take another variable say
**n**and initialize its value to 2. - Take another variable say
**o**and initialize its value to 5. - Loop until the above-declared variable itr value is less than or equal to the given number using the while loop.
- Inside the loop, add the above 3 values m, n, o and store them in a variable say
**rslt**. - Assign the value of n to m.
- Assign the value of o to n.
- Assign the value of
**rslt**to**o**. - Print the value of the
**rslt**separated by spaces using the end function. - Increment the above
**itr**value by 1. - The Exit of the Program.

**Below is the implementation:**

# Give the number N (Limit) as user input using the int(input()) function and # store it in a variable. gvn_numb = int(input("Enter some Random Number = ")) # Take a variable to say itr and initialize its value to 4. itr = 4 print("The above series till the given number{", gvn_numb, "} is :") # Check if the given number is greater than or equal to 1 using the if conditional # statement. if gvn_numb >= 1: # If it is true, then print 1 separated by spaces using the end function. print("1 ", end="") # Check if the given number is greater than or equal to 2 using the if conditional # statement. if gvn_numb >= 2: # If it is true, then print 2 separated by spaces using the end function. print("2 ", end="") # Check if the given number is greater than or equal to 3 using the if conditional # statement. if gvn_numb >= 3: # If it is true, then print 5 separated by spaces using the end function. print("5 ", end="") # Take another variable say m and initialize its value to 1. m = 1 # Take another variable say n and initialize its value to 2. n = 2 # Take another variable say o and initialize its value to 5. o = 5 # Loop until the above-declared variable itr value is less than or equal to the # given number using the while loop. while itr <= gvn_numb: # Inside the loop, add the above 3 values m, n, o and store them in a variable # say rslt. rslt = m + n + o # Assign the value of n to m. m = n # Assign the value of o to n. n = o # Assign the value of rslt to o. o = rslt # Print the value of the rslt separated by spaces using the end function. print(rslt, end=" ") # Increment the above itr value by 1. itr += 1

**Output:**

Enter some Random Number = 8 The above series till the given number{ 8 } is : 1 2 5 8 15 28 51 94
