We are given the sequence \( \left( 2^{2-n} \right)^{\infty}_{n=1} \). Find the recursive formula of such sequence.
\( a_1=2\,;\ a_{n+1}=a_n\cdot\frac12,\ n\in\mathbb{N} \)
\( a_1=2\,;\ a_{n+1}=a_n\cdot2,\ n\in\mathbb{N} \)
\( a_1=2\,;\ a_{n+1}=a_n\cdot2^n,\ n\in\mathbb{N} \)
\( a_1=2\,;\ a_{n+1}=a_n\cdot\frac1{2^n},\ n\in\mathbb{N} \)
