\[S = 655\ руб.\ 35\ коп. =\]
\[= 65\ 535\ коп.\]
\[b_{1} = 1,\ \ b_{2} = 2,\ \ b_{3} = 4,\]
\[\ \ q = \frac{4}{2} = 2\]
\[S_{n} = \frac{b_{1}\left( q^{n} - 1 \right)}{q - 1} = \frac{1 \cdot \left( 2^{n} - 1 \right)}{2 - 1} =\]
\[= 2^{n} - 1\]
\[2^{n - 1} = 65\ 535,\ \ 2^{n} = 65\ 536,\]
\[\text{\ \ }2^{n} = 2^{16},\ \ n = 16\]
