Program to Find the Sum of Natural Numbers from a to b

To find the sum of natural numbers from a to b, you can use the formula for the sum of an arithmetic series, which is given by:

Sum = (n/2) * (first term + last term)

Where: - n = number of terms - first term = a - last term = b

Here's a simple program in Python to calculate the sum of natural numbers from a to b:

def sum_of_natural_numbers(a, b):
    n = b - a + 1  # Number of terms
    first_term = a  # First term
    last_term = b  # Last term
    sum = (n / 2) * (first_term + last_term)  # Sum of the series
    return sum

# Example usage
a = 1
b = 10
result = sum_of_natural_numbers(a, b)
print("The sum of natural numbers from", a, "to", b, "is:", result)

When you run this program with the values of a and b, it will calculate and display the sum of natural numbers from a to b.
