Flow of Control — Question 10

Question 10

Write a short program to print the following series :

(i) 1 4 7 10 .......... 40.
(ii) 1 -4 7 -10 .......... -40

Solution

print("First Series:")
for i in range(1, 41, 3) :
    print(i, end = ' ')

print("\nSecond Series:")
x = 1
for i in range(1, 41, 3) :
    print(i * x, end = ' ')
    x *= -1

Output

First Series:
1 4 7 10 13 16 19 22 25 28 31 34 37 40 
Second Series:
1 -4 7 -10 13 -16 19 -22 25 -28 31 -34 37 -40
