Program to Print Series 0,2,8,14,24,34 …N in Python

Below are the ways to print the series ( 0,2,8,14,24,34 …N) till the given number N in Python:

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 say previous_val and initialize its value to 0.
  • Loop until the above-declared variable itr value is less than or equal to the given number using the while loop.
  • Inside the loop, check if the above itr value is even or not using the if conditional statement.
  • If it is true, calculate the value of itr raised to the power 2 using the pow() function and subtract 2 from it.
  • Store it in the same variable previous_val.
  • Print the value of the above previous_val separated by spaces.
  • Else, If it is false calculate the value of itr raised to the power 2 using the pow() function and subtract 1 from it.
  • Store it in the same variable previous_val.
  • Print the value of the above previous_val separated by spaces.
  • Increment the above itr value by 1.
  • The Exit of the Program.

Below is the implementation:

# Give the number N as static input and store it in a variable.
gvn_numb = 5
# Take a variable to say itr and initialize its value to 1.
itr = 1
# Take another variable say previous_val and initialize its value to 0.
previous_val = 0
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 loop, check if the above itr value is even or not using the if
  # conditional statement.
    if(itr % 2 == 0):
      # If it is true, calculate the value of itr raised to the power 2 using the pow()
          # function and subtract 2 from it.
      # Store it in the same variable previous_val.
        previous_val = pow(itr, 2) - 2
        # Print the value of the above previous_val separated by spaces.
        print(previous_val, end=" ")
    else:
     # Else, If it is false calculate the value of itr raised to the power 2 using the pow()
         # function and subtract 1 from it.
         # Store it in the same variable previous_val.
        previous_val = pow(itr, 2) - 1
        # Print the value of the above previous_val separated by spaces.
        print(previous_val, end=" ")
  # Increment the above itr value by 1.
    itr += 1

Output:

The above series till the given number{ 5 } is :
0 2 8 14 24

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 say previous_val and initialize its value to 0.
  • Loop until the above-declared variable itr value is less than or equal to the given number using the while loop.
  • Inside the loop, check if the above itr value is even or not using the if conditional statement.
  • If it is true, calculate the value of itr raised to the power 2 using the pow() function and subtract 2 from it.
  • Store it in the same variable previous_val.
  • Print the value of the above previous_val separated by spaces.
  • Else, If it is false calculate the value of itr raised to the power 2 using the pow() function and subtract 1 from it.
  • Store it in the same variable previous_val.
  • Print the value of the above previous_val separated by spaces.
  • Increment the above itr value by 1.
  • 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 say previous_val and initialize its value to 0.
previous_val = 0
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 loop, check if the above itr value is even or not using the if
  # conditional statement.
    if(itr % 2 == 0):
      # If it is true, calculate the value of itr raised to the power 2 using the pow()
          # function and subtract 2 from it.
      # Store it in the same variable previous_val.
        previous_val = pow(itr, 2) - 2
        # Print the value of the above previous_val separated by spaces.
        print(previous_val, end=" ")
    else:
     # Else, If it is false calculate the value of itr raised to the power 2 using the pow()
         # function and subtract 1 from it.
         # Store it in the same variable previous_val.
        previous_val = pow(itr, 2) - 1
        # Print the value of the above previous_val separated by spaces.
        print(previous_val, end=" ")
  # Increment the above itr value by 1.
    itr += 1

Output:

Enter some Random Number = 9
The above series till the given number{ 9 } is :
0 2 8 14 24 34 48 62 80
