In the previous article, we have discussed Python Program to Print Series 1 2 5 8 15 28 51 94….N

Given a number N and the task is to print the series** (0 2 6 12 20 30 42…N)** till the given number N in Python.

**Examples:**

**Example1:**

**Input:**

Given Number (Limit) = 9

**Output:**

The above series till the given number{ 9 } is : 0 2 6 12 20 30 42 56 72

**Example2:**

**Input:**

Given Number (Limit) = 10

**Output:**

The above series till the given number{ 10 } is : 0 2 6 12 20 30 42 56 72 90

## Program to Print Series 0 2 6 12 20 30 42…N in Python

Below are the ways to print the series** (0 2 6 12 20 30 42…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 1. - Loop until the above-declared variable itr value is less than or equal to the given number using the while loop.
- Multiply the above
**itr**value with itself and subtract again the itr value from it. - Store it in another variable.
- Print the value of the above result 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 = 9 # Take a variable to say itr and initialize its value to 1. itr = 1 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: # Multiply the above itr value with itself and subtract again the itr value from it. # Store it in another variable. k = (itr*itr)-itr # Print the value of the above result separated by spaces using the end function. print(k, end=" ") # Increment the above itr value by 1. itr += 1

**Output:**

The above series till the given number{ 9 } is : 0 2 6 12 20 30 42 56 72

### 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 1. - Loop until the above-declared variable itr value is less than or equal to the given number using the while loop.
- Multiply the above
**itr**value with itself and subtract again the itr value from it. - Store it in another variable.
- Print the value of the above result 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 1. itr = 1 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: # Multiply the above itr value with itself and subtract again the itr value from it. # Store it in another variable. k = (itr*itr)-itr # Print the value of the above result separated by spaces using the end function. print(k, end=" ") # Increment the above itr value by 1. itr += 1

**Output:**

Enter some Random Number = 10 The above series till the given number{ 10 } is : 0 2 6 12 20 30 42 56 72 90
