Section 11-3

 A sequence is a list of numbers in a particular order.  Each number in a sequence is called a term.  A geometric sequence is when each term is found by multiplying the previous term by a constant (called the common ratio).

 a n = nth term  a 1 = first term  r = common ratio  n is any positive integer

 Find the indicated term of the geometric sequence with

 Write an equation for the nth term of the geometric sequence 64, 16, 4, …

 Write an equation for the nth term of the geometric sequence 4, -12, 36, …

 The missing term(s) between two non- successive terms of a geometric sequence are called geometric means.

 Find three geometric means between 3.12 and 49.92

 Find three geometric means between 4 and 324
