Geometric Sequences
Geometric Sequences 1. Core Concepts Definition: A sequence is called a Geometric Sequence if the ratio of any term (from the 2nd term) to its preceding term is a constant. This constant is called the Common Ratio ( q ), ( q eq 0 ). Mathematical Expression: (a(n))/(a(n - 1)) = q …
