Answer 1

Resposta:

PG => ( 1,  2/3 , 4/9, 8/27, 16/81)

Explicação passo-a-passo:

$a_{1} = 1\\\\\a_{2} = a_{1} . q => 1 . \frac{2}{3} => a_{2} = \frac{2}{3} \\\\a_{3} = a_{2} . q => \frac{2}{3}. \frac{2}{3} => a_{3} = \frac{4}{9} \\\\a_{4} = a_{3} . q => \frac{4}{9}. \frac{2}{3} => a_{4} = \frac{8}{27} \\\\a_{5} = a_{4} . q => \frac{8}{27}. \frac{2}{3} => a_{5} = \frac{16}{81}$
