Knowledge and Understanding 1. Find the first 5 terms of the sequence given by the following general terms: a) t = 3n +4 b) , = 2, tz = 3, t,+2 = tn+1 - 2t (5) 2. For the arithmetic sequence with t; = -49, ts =-84, find: i) the first term a ii) the common difference d iii) the general term t (6) 3. For the geometric sequence 9,3,1, -,... find: i) the common ratio r ii) the general term t iii) to ( 4 ) Thinking and Inquiry 4. Suppose you earn $0.30 cents on February 1, $0.70 cents on February 2, $1.10 on February 3, and so on. How much money will you earn on February 28? (3) 5. How many multiples of 4 are there between 21 and 402? Application 6.
