\[p(1)=1\]

\[p(n)=1-\frac{p(n-1)}{2}\]

Compute and plot p(n) for \(n=1,2,\ldots , 20\). What inference do you draw about the terms p(n)?

\[a(1)=1\]

\[a(n)=\frac{1+1}{(1+a(n-1))}\]

Compute a(n) and \(a(n)^2-2\) for \(n=1,2,\ldots , 20\). What inference do you draw about the terms \(a(n)^2-2\)?

The graph is different with points that are increasing and decreasing. \(a(n)=\frac{1+1}{(1+a(n-1))} \) is a horizontal line while \(a(n)^2-2\) is a more complex solution with a different inf(a(n)) and sup(a(n)).
