WebA geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio, r. a n = a n − 1 ⋅ r o r a n = a 1 ⋅ r n − 1 Example Write the first five terms of a geometric sequence in which a 1 =2 and r=3. We use the first given formula: a 1 = 2 a 2 = 2 ⋅ 3 = 6 WebIn this activity, students generate two geometric sequences from a mathematical situation. The purpose is to create representations of geometric sequences using tables and graphs. At this time, students do not need to write equations for the situation since that work will be the focus of a future lesson.

WebA geometric sequence is a sequence of numbers in which each term is obtained by multiplying the previous term by a fixed number. It is represented by the formula a_n = … WebUsing Explicit Formulas for Geometric Sequences. Because a geometric sequence is an exponential function whose domain is the set of positive integers, and the common ratio is the base of the function, we can write explicit formulas that allow us to find particular terms. cramer + cramer sàrl
