1 puny Use the pattern of "common ratios" to find the requested term from each sequence. Try to do it without finding all the terms in between! 1. Consider the sequence a {4, 20, 100, 500, 2500,...) a. What is the common ratio?
b. What is the 13th term in the sequence?
2. Consider the sequence b= {4,1,1/4,1/6,1/64,...}
a. What is the common ratio? b. What is the 27th term in the sequence? 3. Consider the sequence c = {5,-15,45,-135,405,...}
a. What is the common ratio? b. What is the 47th term in the sequence? 4. Consider the sequence d = {9,-9/5,9/25,-9/25,9/625,...}
a. What is the common ratio? b. What is the 82nd term in the sequence?
