Para encontrar el octavo término de la secuencia, primero debemos determinar el patrón de la secuencia. Examinemos la secuencia: 8, 4, 2 Observamos que cada término es la mitad del término anterior: \(8 \div 2 = 4\) \(4 \div 2 = 2\) Este patrón indica que la secuencia es una secuencia geométrica con una razón común de \( \frac{1}{2} \). Para encontrar el octavo término, podemos usar la fórmula para el \(n\)ésimo término de una secuencia geométrica: \[ a_n = a_1 \times r^{(n-1)} \] Dónde: - \( a_n \) es el \(n\)ésimo término, - \( a_1 \) es el primer término, - \( r \) es la razón común, y - \( n \) es el número del término. Para esta secuencia: - \( a_1 = 8 \) (el primer término) - \( r = \frac{1}{2} \) (la razón común) - \( n = 8 \) (el número de término que nos interesa) Inserte estos valores en la fórmula: \[ a_8 = 8 \times \left(\frac{1}{2}\right)^{(8-1)} \] \[ a_8 = 8 \times \left(\frac{1}{2}\right)^{7} \] \[ a_8 = 8 \times \left(\frac{1}{128}\right) \] \[ a_8 = \frac{8}{128} \] \[ a_8 = \frac{1}{16} \] Entonces, el octavo término de la secuencia es \( \frac{1}{16} \).

25) Paulo saves R$250.00 per month and keeps the money in a safe in his own home. At the end of 12 months, deposit the total saved into the savings account. Consider that, each year, deposits are always carried out on the same day and month; the annual yield on the savings account is 7%; and, the yield total is obtained by the interest compounding process. So, the amount that Paulo will have in his savings account after 3 years, from the moment you started saving part of your money monthly, it will be A) R$6,644.70. B) R$ 9,210.00. C) R$ 9,644.70. D) R$ 10,319.83. E) R$ 13,319.83
