so, like APL
Yes but that works for this equation only because its characteristic polynomial is x²-x-1, whose roots are the golden ratio and its conjugate. For a general recurrence equation (order notwithstanding) you can get…
This was exactly my thought. The use of "returned" reveals a clinging to a lie that's still lurking in the background.
