Answer 1

myStream.zipWithIndex                    //attach index to every element
        .filter(x => (1 + x._2) % n > 0) //adjust index, remove every nth
        .map(_._1)                       //remove index

Oops, almost forgot: filter and map can be combined.

myStream.zipWithIndex
        .collect{case (e,x) if (1 + x) % n > 0 => e}
