You alright for number two and I guess that by computing some value you can do number 3 alone.
(c) Consider the linear recurrence sequencex1 =23,xn+1 =1.3xn − 12(n =1,2,3,...).(i)Find a closed form for the sequence.(ii) Use the closed form to find the eighth term of the sequence,correct to four significant figures.(iii) Describe the long-term behaviour of the sequence.
