Plz plz someone help me out with this

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

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

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

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

What is the simplified form of ?

Natalija [7]

Let's set it up like this:
$\frac{\frac{x}{3}-\frac{y}{4}}{\frac{x}{4}+\frac{y}{3}}$
Find the LCD, which is 12, and adjust them according to that.
$=\frac{\frac{4x-3y}{12}}{\frac{3x+4y}{12}}$
Divide.
$=\frac{\left(4x-3y\right)\cdot \:12}{12\left(3x+4y\right)}$
Cancel the common factor, which is 12.
$=\frac{4x-3y}{3x+4y}$
That would be our answer!

Let me know if you have any questions regarding this problem!
Thanks!
