Consider sequences that consist entirely of [unparseable or potentially dangerous latex formula]'s and [unparseable or potentially dangerous latex formula]'s an that have the property that every run of consecutive [unparseable or potentially dangerous latex formula]'s has even length, and every run of consecutive [unparseable or potentially dangerous latex formula]'s has odd length. Examples of such sequences are [unparseable or potentially dangerous latex formula] and [unparseable or potentially dangerous latex formula] while [unparseable or potentially dangerous latex formula] is not such a sequence. How many such sequences have length of [unparseable or potentially dangerous latex formula]?
