Question

qual o 10 termo da P.g (3,6,12..)

Answer 1

an= a₁.q^(n-1)

an= 10
a₁= 3
q= 6/3= 2
n= 10

a₁₀= 3.2^(9)
a₁₀= 3.512
a₁₀= 1536

Forte abraço!

Answer 2

Olá, boa tarde ☺

Resolução:

$\\A_{n}=a_{1}\times q^{(n-1)} \\A_{10}=3\times 2^{(10-1)} \\ A_{10}= 3 \times 2^{9} \\ A_{10}=3\times512 \\ A_{10}=1536 \\ \\ P.G=(3,6,1224,48,96,192,384,768,1536)$

Bons estudos :)
