Evaluate the expression of a term of a geometric sequence

The video tutorial explains how to write an expression for a specific term in a geometric sequence. It focuses on calculating the ninth term using the formula a_n = a_1 * r^(n-1). The tutorial demonstrates the process of substituting known values into the formula and discusses the rules for multiplying exponents. The final expression for the ninth term is presented, acknowledging that further simplification is not possible due to the presence of a variable.
