Question

Determine a soma de termos da PG(24, 12,...)

Answer 1

Resposta:

$s = \frac{a1}{1 - q} \\ s = \frac{24}{1 - \frac{1}{2} } \\ s = \frac{24}{ \frac{2 - 1}{2} } \\ s = \frac{24}{ \frac{1}{2} } \\ s = 24 \times 2 \\ s = 48$

Explicação passo-a-passo:

soma PG infinita

$q = \frac{12}{24} = \frac{1}{2}$
