Question

como calcular o sexto termo da p.g (4,12,36,...)

Answer 1

$Resolu\c{c}\~ao\to \left\{\begin{array}{ccc}P.G(4,12,36,...)\\\\q_{raz\~ao} = \frac{a_2}{a_1} = \frac{12}{4} = 3\\\\a_6 = a_1*q^{6-1}\\\\a_6 = 4*3^{5}\\\\a_6 = 4*243\\\\ \boxed{\boxed{a_6 =972 }} }\end{array}\right$

Espero ter ajudado. :))

Answer 2

Olá.

$a_n= a_1*q ^{n-1} \\ a_6= 4*3 ^{6-1} \\ a_6= 4*3 ^{5} \\ a_6= 4*243 \\ a_6= 972 <-$

Bons estudos!
