Geometric Sequences
ALGEBRA 1 LESSON 8-6
1. Find the common ratio of the geometric
sequence 3, 6, 12, 24, . . . 2. Find the
next three terms of the sequence 243, 81, 27, 9,
. . . 3. Determine whether each sequence is
arithmetic or geometric. a. 37, 34, 31, 28, . .
. b. 8, 4, 2, 1, . . . 4. Find the
first, fifth, and ninth terms of the sequence
that has the rule A(n) 4(5)n1. 5. Suppose you
enlarge a photograph that is 4 in. wide and 6 in.
long so that its dimensions are 20 larger than
its original size. Write a rule for the length of
the copies. What will be the length if you
enlarge the photograph five times? (Hint The
common ratio is not just 0.2. You must add 20 to
100.)
