We are given a sequence \( \left( a_n \right)^{\infty}_{n=1} \) defined recursively by: \(a_1=0\,;\ a_{n+1}=2-a_n,\ n\in\mathbb{N} \). Find the \( n \)th term of this sequence.
\( a_n=1+(-1)^n,\ n\in\mathbb{N} \)
\( a_n=1+(-1)^{n+1},\ n\in\mathbb{N} \)
\( a_n=1+(-1)^{n-1},\ n\in\mathbb{N} \)
\( a_n=1-1^n,\ n\in\mathbb{N} \)
