Question

Dados "a" e "q" escreva a PG com 4 termos:
A) a1= 3 e q=4
B)a1= -2 e q=3
C)a1= 1/5 e q=2

Answer 1

A) a1= 3 e q=4

3×4= 12 ; 12×4= 48 ; 48×4= 192

PG ( 3, 12, 48, 192)

B)a1= -2 e q=3

-2× 3= -6

-6× 3= -18

-18× 3= -54

PG ( -2, -6, - 18, - 54)

C)a1= 1/5 e q=2

$\frac{1}{5} \times \frac{2}{1} = \frac{2}{5}$

$\frac{2}{5} \times \frac{2}{1} = \frac{4}{5}$

$\frac{4}{5} \times \frac{2}{1} = \frac{8}{5}$

PG

$( \frac{1}{5}. \frac{2}{5} . \frac{4}{5} . \frac{8}{5} )$
