Question

Dada pg ( 4 096, 2 048, 1024,....) determine a soma dos 10 primeiros termos.​

Answer 1

Resposta:

8184

Explicação passo-a-passo:

$S=\frac{a1(q^n-1)}{q-1} \\S=\frac{4096(\frac{1}{2} ^{10}-1) }{\frac{1}{2}-1 } \\S=\frac{4096(\frac{1}{1024}-1)}{-\frac{1}{2} } \\S= \frac{4-4096}{-\frac{1}{2} } \\S=\frac{-4092}{-\frac{1}{2} }\\S= 8184$
