In the previous module, we define arithmetic sequence and give the next For example: Find the next three terms of the arithmetic sequence: 3, 8, 13, term by adding a constant number. 18,.. a. The terms are a = 3, a₂ = 8, a3 = 13, and a = 18. So, we will be finding as, a6, and a7. b. The common difference (d) in the sequence is 5. c. To get the next three terms, add 5 to each of the preceding term. Thus: as = a4 + 5 = 18 + 5 = 23 a6 = a5 + 5 = 23 + 5 = 28 a7 = a6 + 5 = 28 + 5 = 33 What about if the problem is to find the 100th term or the 250th term? Can much of your time and effort. There is a short cut in doing this and that is you find the terms? Using the process that is illustrated above will take one of the focus of this module.solution​
