Calculating Successive Halving in Signal Filtration

A signal processing engineer is analyzing a cascade of 14 acoustic filters. The initial filter has a frequency tolerance of 64 Hz. Each subsequent filter halves the tolerance of the previous one, forming a geometric sequence with a common ratio of r=12r = \frac{1}{2}. Using the general term formula, calculate the frequency tolerance of the 14th filter. Briefly state the formula you used, your substitution, and your final answer as a fraction.
