Let {an }n>o be a sequence defined by a = n² + 2n − 3 for every n>0 a) Find the firsts 3 (elements) elements of the sequence. b) Show that the sequence satisfies the recurrence relation An = 2an-1 − An-2 +2 for every n ≥ 2. c) Find a closed formula for the first difference of the sequence {an}n>0² i.e., Δαπ = an+1-an for every n > 0.
