Python Program to Print Series 6, 11, 21, 36, 56...n

In the previous article, we have discussed Python Program to Print Series 1, 2, 4, 8, 16, 32…n
Given a number N and the task is to print the series (6,11,21,36,56…N) for the given number N in Python.

Examples:

Example1:

Input:

Given Number = 6

Output:

The above series till the given number{ 6 } is :
6 11 21 36 56 81

Example2:

Input:

Given Number = 10

Output:

The above series till the given number{ 10 } is :
6 11 21 36 56 81 111 146 186 231

Program to Print Series 6,11,21,36,56…n in Python

Below are the ways to print the series (6,11,21,36,56…N) for the given number N in Python:

Using While Loop (Static Input)
Using While loop (User Input)

Method #1: Using While Loop (Static Input)

Approach:

Give the number N as static input and store it in a variable.
Take a variable to say itr and initialize its value to 1.
Take another variable to say previos_val and initialize its value to 6.
Take the other variable to say gvn_diffence and initialize its value to 5 (which is the common difference).
Loop until the above-declared variable itr value is less than or equal to the given number using the while loop.
Inside the while loop, print the value of the above previos_val value separated by spaces.
Add the given difference to the previous value and store it in the same variable previos_val.
Add 5 to the given difference and store it in the same variable.
Increment the value of the above itr value by 1 and store it in the same variable.
The Exit of the Program.

Below is the implementation:

# Give the number N as static input and store it in a variable.
gvn_numb = 6
# Take a variable to say itr and initialize its value to 1.
itr = 1
# Take another variable to say previos_val and initialize its value to 6.
previos_val = 6
# Take the other variable to say gvn_diffence and initialize its value to 5
# (which is the common difference).
gvn_diffence = 5
print("The above series till the given number{", gvn_numb, "} is :")
# 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 while loop, print the value of the above previos_val value
        # separated by spaces.
    print(previos_val, end=" ")
    # Add the given difference to the previous value and store it in the same
    # variable previos_val.
    previos_val = previos_val + gvn_diffence
    # Add 5 to the given difference and store it in the same variable.
    gvn_diffence = gvn_diffence + 5
    # Increment the value of the above itr value by 1 and store it in the
    # same variable.
    itr += 1

Output:

The above series till the given number{ 6 } is :
6 11 21 36 56 81

Method #2: Using While loop (User Input)

Approach:

Give the number N 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 1.
Take another variable to say previos_val and initialize its value to 6.
Take the other variable to say gvn_diffence and initialize its value to 5 (which is the common difference).
Loop until the above-declared variable itr value is less than or equal to the given number using the while loop.
Inside the while loop, print the value of the above previos_val value separated by spaces.
Add the given difference to the previous value and store it in the same variable previos_val.
Add 5 to the given difference and store it in the same variable.
Increment the value of the above itr value by 1 and store it in the same variable.
The Exit of the Program.

Below is the implementation:

# Give the number N 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 1.
itr = 1
# Take another variable to say previos_val and initialize its value to 6.
previos_val = 6
# Take the other variable to say gvn_diffence and initialize its value to 5
# (which is the common difference).
gvn_diffence = 5
print("The above series till the given number{", gvn_numb, "} is :")
# 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 while loop, print the value of the above previos_val value
        # separated by spaces.
    print(previos_val, end=" ")
    # Add the given difference to the previous value and store it in the same
    # variable previos_val.
    previos_val = previos_val + gvn_diffence
    # Add 5 to the given difference and store it in the same variable.
    gvn_diffence = gvn_diffence + 5
    # Increment the value of the above itr value by 1 and store it in the
    # same variable.
    itr += 1

Output:

Enter some Random Number = 10
The above series till the given number{ 10 } is :
6 11 21 36 56 81 111 146 186 231
