1. Honors Precalculus Day 3 Section 11.3 Geometric Sequences The end of new material…BOO!!! 3/12/2016

2. Geometric Sequence nth term of an geometric sequence Sum of the first n terms of a finite geometic sequence Sum of the terms of an infinite geometric sequence Has a common ratio (r) between terms ex: 2, 10, 50,... r = 5 nth term 1st term common ratio 625, 250, 100, 40, 16... This formula only applies if r is a fraction. (between -1 and 1)

3. 1. Find the 7 th term of 0.1, 1.0, 10.0, … 2. Write an expression to find the sum of r = 10

4. 3. Find the sum of 4. Find the sum of r = 3
