You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

2, 3, ['a', '34', 'f', '931', '7', '3432', '13245', '762']
Solution: 34, 7, 762
Why? Here, starting from 2nd element every 3rd element from the list are '34', '7', and '762'.

New input: 1, 2, ['839', 'N', '3569', 'v', '7689', 'E', 'L', 'h', '8641']
Solution:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
