Let $\alpha$ and $\beta$ be the roots of $x^{2}-3 x+p=0$ and $\gamma$ and $\delta$ be the roots of $x^{2}-6 x+q=0 .$ If $\alpha$ $\beta, \gamma, \delta$ form a geometric progression. Then ratio $(2 q+p):(2 q-p)$ is
$3: 1$
$33: 31$
$9: 7$
$5: 3$
Which term of the $GP.,$ $2,8,32, \ldots$ up to $n$ terms is $131072 ?$
The sum can be found of a infinite $G.P.$ whose common ratio is $r$
The terms of a $G.P.$ are positive. If each term is equal to the sum of two terms that follow it, then the common ratio is
If $a,\;b,\;c$ are in $A.P.$, $b,\;c,\;d$ are in $G.P.$ and $c,\;d,\;e$ are in $H.P.$, then $a,\;c,\;e$ are in
If the sum of the $n$ terms of $G.P.$ is $S$ product is $P$ and sum of their inverse is $R$, than ${P^2}$ is equal to
