How many frames are in an animated TV series?

I've been knowing how many individual animation frames are in an animated TV series?

in an article for How TV animation works, it said that it has 30,000 animation frames but that only depends how many frames that they have and how they animate it, animated TV series is usually animate on 2s using traditional animation, Anime however is most often animate on 3s, can you please answer this question of how many individual drawings are in an animated TV series?
