Esistenza o non esistenza di limiti

Una domanda che può sembrare banale, ma che mi sta tartassando di dubbi. Se ho la successione (-1)^k! il suo limite tenderà a uno definitivamente, vero?

Giusto, mio errore per "limite che tende" e "limite uguale a" :!:

Però non capisco perché se ho la sottosuccesione con l'esponente dispari esce -1. In effetti (2k+1)! con k>1 definitivamente è sempre un numero pari, perciò il limite dovrebbere essere uguale a 1 definitivamente. Scusami se insisto ma vorrei capire se dico boiate o meno :roll:
