Answer:

option D

$a_{1}=6561 and a_{n}=\frac{1}{3}a_{n-1}$

Step-by-step explanation:

$a_{3} = 729\\\\a_{4} = 243\\\\r = \frac{a_{4}}{a_{3}}\\\\r=\frac{243}{729}\\\\r=\frac{1}{3}$

Recursive rule: Next term is obtained by multiplying (1/3) wiht the previous term

$a_{n}=\frac{1}{3}*a_{n-1}$

$a_{3} = \frac{1}{3}*a_{2}\\\\\\729 = \frac{1}{3}*a_{2}\\\\\\729*3=a_{2}\\\\a_{2} = 2187\\\\\\$

$a_{2}=\frac{1}{3}*a_{1}\\\\\\2187=\frac{1}{3}*a_{1}\\\\\\2187*3=a_{1}\\\\a_{1}=6561$

telo118 [61]

Answer:

$\frac{1}{12}$

Step-by-step explanation:

P(tail) = $\frac{1}{2}$

P(2) = $\frac{1}{6}$

P(tail and 2 ) = $\frac{1}{2}$ × $\frac{1}{6}$ = $\frac{1}{12}$
