##### ► Python program to print Arithmetic progression

Steps followed:
1. Take the first number, common difference and the number of items in progression as input from user
2. get last item of the sequence using below formula
Xn = a + d(n−1)
3. use range function to get the Arithmetic progression

Program
``````#Python program to print Arithmetic progression

# Take the first number, common difference and the number of items in progression as input from user
first_number = int(input("enter the first number of sequence: "))
common_difference = int(input("enter the common difference of the sequence: "))
items_in_sequence= int(input("enter the number of items to be printed in the sequence: "))

#get last item of the sequence
last_number = first_number + common_difference * (items_in_sequence-1)

# range function to get the Arithmetic progression
for i in range(first_number,last_number+1,common_difference):
print(i,end=",")``````

Output
``````enter the first number of sequence: 5
enter the common difference of the sequence: 6
enter the number of items to be printed in the sequence: 20
