Defined by a simple nested recurrence and an initial condition, the sequence looks approximately linear, though with a lot of noise. But, nobody even knows whether the sequence is infinite. In the years since Hofstadter published his sequence, various people have found variants with predictable behavior. Oftentimes, the resulting sequence looks complicated but provably grows linearly. Other times, the sequences are eventually linear recurrent.
