# Math Help - how to show that the X_kn is a markov chain if X_n is a markov chain

1. ## how to show that the X_kn is a markov chain if X_n is a markov chain

$(X_{n})_{n\geq0}$ is a discrete time markov chain with Transition matrix P

show that $(X_{kn})_{n\geq0}$ is a markov chain with transition matrix $P^{k}$

Are you asking for a complete course in Markov chains?
BTW: Markov was real mathematician so please capitalize his name.
You can easily do a web-search on this topic.

3. ## anyone

anyone can try this problem?
