When should you choose a recursive algorithm over an iterative algorithm?
What are the conditions under which a recursive algorithm will stop calling itself?
A recursive sequence is defined by -
d k = 6 d k − 1 + 3 , for all integers k ≥ 2
and d1 = 2
Use iteration to guess an explicit formula for the above sequence.
