Question

find the area of square whose area is 7tn term in GP 2,√8,4,...........

Answer 1

$t \frac{}{7} = a {r}^{n - 1}$
$t \frac{}{7} = 2 \times { (\sqrt{2} )}^{7 - 1}$
$t \frac{}{7} = 2 \times { (\sqrt{2}) }^{6}$
$t\frac{}{7} = 2 \times 8$
$t\frac{}{7}=16$
$length\:of\:side\:of\:square \:is=\sqrt{16}=4$
