Geometric Sequences as Exponential Functions
A geometric sequence can be written as an exponential function: where is the initial value and is the base of the exponential expression. Key formulas include expressions such as a_n = a_1 \cdot r^{n-1}. This concept is part of Big Ideas Math, Algebra 2 for Grade 8 students, covered in Chapter 8: Sequences and Series.
Key Concepts
