Considerando a pg (4,12,36,198,32,.....)encontre o 7 termo

Answer 1

$\textup{Boa noite!}$

Entendo que seja; (4, 12, 36, 108, 324...)

$\textup{a1}\rightarrow\textup{4}$
$\textup{N}\rightarrow\textup{7}$
$\textup{Q}\rightarrow\textup{A2}\div \textup{A1}\rightarrow\textup{12/4} = \textup{3}$

$\textup{An}=\textup{a1}\ast q^{(n-1)}$
$\textup{A7}=\textup{4}\ast3^{(7-1)}$
$\textup{A7}=\textup{4}\ast3^{6}$
$\textup{A7}=\textup{4}\ast 729$
$\textup{A7}=\textup{2916}$
