/*
In this problem you will test your knowledge of Java loops. Given three integers aa, bb, and nn, output the following series:

a+20b,a+20b+21b,......,a+20b+21b+...+2n−1ba+20b,a+20b+21b,......,a+20b+21b+...+2n−1b

Input Format
The first line will contain the number of testcases t. Each of the next tt lines will have three integers, aa, bb, and nn.

Constraints:
0≤t≤5000≤t≤500
0≤a,b≤500≤a,b≤50
1≤n≤151≤n≤15

Output Format
Print the answer to each test case in separate lines.

Sample Input
2
0 2 10
5 3 5
Sample Output
2 6 14 30 62 126 254 510 1022 2046
8 14 26 50 98
