Question

Determine o sétimo termo da PG (−96, −24, −6, … ).

Answer 1

Explicação passo-a-passo:

$an = a1 \times q {}^{(n - 1)}$

$a7 = - 96 \times \dfrac{ - 24}{ - 96} {}^{(7 - 1)}$

$a7 = - 96 \times (\dfrac{24 {}^{ \div 24} }{96 {}^{ \div 24} } ) {}^{6}$

$a7 = - 96 \times (\dfrac{1}{4} ) {}^{6}$

$a7 = - 96 \times \dfrac{1}{4096}$

$a7 = - \dfrac{96}{4096}$

$a7 = - \dfrac{96 {}^{ \div 32} }{4 96 {}^{ \div 32} }$

$a7 = - \dfrac{3}{128}$>>>resposta
