Description
Returns a fibonacci series series.
fibo-ser produces a list of terms starting with seed1 and seed2 and produces new terms by adding the previous two, until the series reaches limit or would exceed limit in its next term.
Additionally, you can specify two optional inputs begin and end , which will cause fibo-ser to return only the range of elements of the series between the two inputs (just like geometric-ser
Examples
