The position(distance from the first tree) follows the following series
0 6 10 17 22 30 36....

Input format:
Input is an integer which corresponds to number of willow trees, n.

Output format:
Output is the series that contains 'n' numbers.

Sample Input 1:
7
Sample Output 1:
0 6 10 17 22 30 36

Sample Input 2:
5
Sample Output 2:
0 6 10 17 22

//Program
