\[b_{1} = 2;\ \ b_{5} = 162;\ \ q < 0.\]
\[b_{5} = b_{1} \cdot q^{4}\]
\[q^{4} = \frac{b_{5}}{b_{1}} = \frac{162}{2} = 81\]
\[q = - 3.\]
\[S_{6} = \frac{b_{1} \cdot \left( q^{5} - 1 \right)}{q - 1} =\]
\[= \frac{2 \cdot \left( ( - 3)^{5} - 1 \right)}{- 3 - 1} =\]
\[= \frac{162 \cdot ( - 243 - 1)}{- 4} = 2 \cdot 61 =\]
\[= 122.\]
\[Ответ:122.\]
