Write a recursive formula for the pattern shown above. \[ \begin{array}{l} a_{1}=1 \\ a_{n}=a_{n-1}+2 \\ a_{1}=1 \\ a_{n}=2 a_{n-1}+1 \\ a_{1}=1 \\ a_{n}=2 n-1 \\ a_{1}=1 \\ a_{n}=2 n+1 \\ a_{n}=2 n-1 \end{array} \] A sequence is arithmetic if an only if the difference between any two consecutive terms is the same as the difference between any other two consecutive terms.
