So this is a line from the anime Oregairu. From what I know, I would say ある
and あり mean the same thing. However, I could be wrong so is there any special
reason why 'ari' was used first and 'aru' was used second in this sentence?

question
meaning sentence
青春とは噓であり、悪である　‐　あり　vs　ある？
青春とは噓であり、悪である is a single sentence.

The first あり is an example of using the masu-stem as a connector similar to
the te-form. See also [this](https://japanese.stackexchange.com/a/54134/17571)
and [this answer](https://japanese.stackexchange.com/a/41142/17571).
