4.15 Introducing Geometric Sequences
The first two sequences are increasing, and the second two are decreasing
Practice this chapterThe first two sequences are increasing, and the second two are decreasing Geometric sequences can get larger or smaller
You used a common ratio to find the pattern to complete the sequence Examine the patterns of numbers given below
first two sequences — increasing, and the second two are decreasing.
Be able to find missing terms in a geometric sequence; compare the quotients. If they are the same, a common ratio exists and the sequence is geometric.
