Question 1 A sequence is defined recursively as follows. an+1 = 2¹+ an-1 where n > 1. Part a) Reindex the recursively defined sequence by substituting n - 1 for n. Part b) Then verify that the first value of n in the reindexed relation also gives a₂ = 2 + ao and consequently the given recurrence relation and the given recurrence relation both produce the same sequence.
