Question

Qual é o 6° termo da PG ( 512, 256 .... ) preciso da conta

Answer 1

Olá.

Dados:

• a1 = 512
• q = 256/512 = 0,5

$a_{6} = a_{1} \times q^{5} \\ a_{6} = 512 \times 0,5^{5} \\ a_{6} = 16$

Bons estudos.

Answer 2

$(512,256,...)\\q= \frac{256}{512}= \frac{1}{2}\\\\ an=a1.q^n^-^1\\a6=512.( \frac{1}{2})^6^-^1\\a6=512( \frac{1}{2})^5\\a6=512( \frac{1}{32})\\a6= \frac{512}{32}\\\\a6=16\\O\ sexto\ termo\ e\´\ 16.$
