Step-by step explanation:

That's a great question. Look for things such as these:

x=x (infinite solution)

x=12 (one solution)

x+3 = x + 5 (no solutions)

What is the recursive rule for this geometric sequence?

saveliy_v [14]

The objective here is to find $r$ (so called common ratio):
$r=a_{n}/a_{n-1}=a_{2}/a_{1}= \frac{3}{2} : 3 = \frac{3}{2} * \frac{1}{3} = \frac{1}{2}$
So assuming the first element of sequence is 3 (as you mentioned) we now can define the recursive rule for this geometric sequence:
$a_{1}=3; a_{n}=\frac{1}{2}a_{n-1}$

krok68 [10]

X = 14

18 + 18 = 36
64 - 36 = 28
28 divided by 2 = 14
