//Task You are given q queries in the form of a, b, and n For each query, print the series corresponding to the given a, b, and n values as a single line of n space-separated integers.
//
//Input Format
//
//The first line contains an integer, q denoting the number of queries. 
//Each line i of the q subsequent lines contains three space-separated integers describing the respective a-th b-th and n-th values for that query.
//
//Constraints
// 0<= q <= 500
// 0<= a,b <= 50
// 1<= n <= 15

//Output Format
//
//For each query, print the corresponding series on a new line. Each series must be printed in order as a single line of n space-separated integers.
//
//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
