In this task, you are given inputs k, i, and A, where k and i are integers and A is a list. You need to find every ith element of A starting from the kth element. The process stops when the position of the next ith element exceeds the length of the list.

Ex Input:
2, 3, ['h', 'v', '6481', 'u', '5245', '4213', '4083', 'H', 'B', '4189', 'R', 'C', 'A', '2103', '5481', '487', '1215']

Ex Output:
v, 5245, H, R, 2103, 1215
