Math 116 In-Class Worksheet: Convergence of Sequences Directions: This worksheet is meant to be completed in groups, but you may work at your own pace. No leaving until class is done! 1) Remember that we were trying to solve the differential equation I claimed that we needed sequences to solve this equation. Let's start with a very basic kind of sequence called a geometric sequence. For such a sequence, any given term is a fixed multiple of the previous term; so if thenth termis anand the (n + 1)st term. is an+1, there is a number㧠called the ratio with an So for example, the sequence (-1 lthat we saw in the last worksheet has n+1 an and so is a geometric sequence. This may look pretty simple, but it will eventually be the basis by which we can ensure that functions constructed with sequences make sense. Check whether the following-sequences are geometric or not, and if so, find the ratio r. 2. 2 2h b) 2. 2. (-5)n+2 12 (n+4) - ht in) 2n+2 12n
