Answer 2

Answer:

$your \: ans = - 2 \sqrt{2}$

Step-by-step explanation:

$\bf\ G.p \: series \: a + {ar}^{2} + .............. + {ar}^{n - 1} \\ \\ \bf\ here \: a \implies \frac{1}{ \sqrt{2} } \\ \\ \bf\ {ar} \implies - 2 \\ \\ \bf\ {ar}^{2} \implies \frac{8}{ \sqrt{2} } \\ \\ \bf\ common \: ratio(r) = \frac{ ar}{a} \\ \\ \bf\ \implies \frac{ - 2}{ \frac{1}{ \sqrt{2} } } \\ \\ \huge\red{\mathtt{ \implies - 2 \sqrt{2} }}$
