Java Loops II

/* We use the integers a, b,c and  to create the following series:
You are given  queries in the form ofa , b, cand . For each query, print the series corresponding to the given a ,b ,c and  values as a single line of  space-separated integers.
Sample Input

2
0 2 10
5 3 5
Sample Output

2 6 14 30 62 126 254 510 1022 2046
