Question

me ajudem!!!! complete as lacunas da seguinte pg: (2,__,__,__,__,__,1458)

Answer 1

 vamos calcular a razão = q

$a_n=a_7=1458 \\ a_1=2 \\ n=7 \\ q=? \\ \\ termo~~geral \\ \\ a_n=a_1.q^{n-1} \\ \\ 1458=2.q^{7-1} \\ \\ 1458=2.q^6 \\ \\ 1458\div2=q^6 \\ \\ q^6=729 \\ \\ q= \sqrt[6]{729} \\ \\ q= \sqrt[6]{3^6 } \\ \\ q=3$ 

se a razão é 3

multiplica cada termo  anterior por 3

$P.G.(2,\underline6,\underline1\underline8,\underline5\underline4,\underline1\underline6\underline2,\underline4\underline8\underline6,1458)$
