Python program to find Sum of Arithmetic Progression Series

first_Num = int(input("Enter First Number of an A.P Series: "))
Total_num = int(input("Enter the Total Numbers in this A.P Series: "))
diff = int(input("Enter the Common Difference: "))
# Calculation
total = (Total_num * (2 * first_Num + (Total_num - 1) * diff)) / 2
tn = first_Num + (Total_num - 1) * diff
# Print the Output
print("\nThe Sum of Arithmetic Progression Series = " , total)
print("The tn Term of Arithmetic Progression Series = " , tn)

OUTPUT:

Enter First Number of an A.P Series: 5
Enter the Total Numbers in this A.P Series: 6
Enter the Common Difference: 15
The Sum of Arithmetic Progression Series =  255.0
The tn Term of Arithmetic Progression Series =  80
