Answer:

$the \: recursive \: formula \: is \\ tn = 6( {4}^{n - 1} )$

Answer is given below with explanations.

Step-by-step explanation:

$the \: given \: geometric \: sequence \: is \\ 6, \: - 24, \: 96, \: - 384 \\ the \: first \: term \: is \: 6 \: and \: the \: common \: ratio \: is \: - 4 \\ the \: {n}^{th} term \: of \: the \: geometric \: sequence \: is \\ tn = a {r}^{n - 1} \\ here \: first \: term \:( a) = 6 \\ common \: ratio \: (r) = - 4 \\ on \: substituting \: the \: values \: in \: formula \\ tn = 6( { - 4}^{n - 1} ) \\ the \: above \: mentioned \: formula \: is \: \\ the \: recursive \: formula \: \\ for \: geometric \: sequence.$

Answer:

CD=9

Step-by-step explanation:

ΔABD=>

AD²=AB² + BD² [Pythagorean Theorem]

BD²= AD²-AB²

BD²=9²-3²

BD²=72

BD=√72=6√2....(1)

ΔBCD=>

CD²=BD²+BC²

CD²=(6√2)² + 3²

CD²=72+9

CD²=81

CD=√81

CD=9
