In the previous article, we have discussed Python Program to Find the Sum of Series 3+7+13+21…..+N

Given a number N and the task is to find the sum of the given series** (1+1/3+1/5+1/7+…..1/(N+2))** for the given number in Python.

**Examples:**

**Example1:**

**Input:**

Given Number = 25

**Output:**

The total sum of the series till the given number { 25 } = 2.2643528386481675

**Example2:**

**Input:**

Given Number = 14

**Output:**

The total sum of the series till the given number { 14 } = 1.9551337551337549

## Program to Find Sum of Series 1+1/3+1/5+1/7+…..1/(N+2) in Python

Below are the ways to find the sum of the given series** (1+1/3+1/5+1/7+…..1/(N+2)) **for the given number 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 say
**resltsum**which gives the sum of the given series till N and initialize its value to 0.0 (to get the floating-point number). - Take another variable say
**k**and initialize its value with 1. - Loop until the value of
**k**is less than or equal to the given number using the while loop. - Inside the loop, Add 1 divided by
**k**to the above-initialized resltsum and store it in the same variable resltsum. - Increment the value of
**k**by 2 and store it in the same variable**k.** - Print the
**resltsum**value which is the result of the series till the given Number N. - The Exit of the Program.

**Below is the implementation:**

# Give the number N as static input and store it in a variable. gvn_numb = 25 # Take a variable say resltsum which gives the sum of the given series till N and # initialize its value to 0.0 (to get the floating-point number). resltsum = 0.0 # Take another variable say k and initialize its value with 1. k = 1 # Loop until the value of k is less than or equal to the given number using the while loop. while(k <= gvn_numb): # Inside the loop, Add 1 divided by k to the above-initialized resltsum and # store it in the same variable resltsum. resltsum += 1/k # Increment the value of k by 2 and store it in the same variable k. k += 2 # Print the resltsum value which is the result of the series till the given Number N. print( "The total sum of the series till the given number {", gvn_numb, "} = ", resltsum)

**Output:**

The total sum of the series till the given number { 25 } = 2.2643528386481675

### 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 say
**resltsum**which gives the sum of the given series till N and initialize its value to 0.0 (to get the floating-point number). - Take another variable say
**k**and initialize its value with 1. - Loop until the value of
**k**is less than or equal to the given number using the while loop. - Inside the loop, Add 1 divided by
**k**to the above-initialized resltsum and store it in the same variable resltsum. - Increment the value of
**k**by 2 and store it in the same variable**k.** - Print the
**resltsum**value which is the result of the series till the given Number N. - 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 say resltsum which gives the sum of the given series till N and # initialize its value to 0.0 (to get the floating-point number). resltsum = 0.0 # Take another variable say k and initialize its value with 1. k = 1 # Loop until the value of k is less than or equal to the given number using the while loop. while(k <= gvn_numb): # Inside the loop, Add 1 divided by k to the above-initialized resltsum and # store it in the same variable resltsum. resltsum += 1/k # Increment the value of k by 2 and store it in the same variable k. k += 2 # Print the resltsum value which is the result of the series till the given Number N. print( "The total sum of the series till the given number {", gvn_numb, "} = ", resltsum)

**Output:**

Enter some Random Number = 14 The total sum of the series till the given number { 14 } = 1.9551337551337549
