\

The sequence is \"\".

\

The first term is \"\".

\

The second term is \"\".

\

The third term is \"\".

\

The fourth term is \"\".

\

The fifth term is \"\".

\

These terms continue to decrease and they do not approach a finite number.

\

Therefore, the sequence is divergent.

\

The sum of the first five terms is \"\" or \"\".
