Answer 1

Answer: $a_n=\frac{3}{2^n}$

Step-by-step explanation:

1. To find the rule of the sequence shown in the problem, you can observe the change that occurs from a number to the other number:

- The numerator does not change.

- The denominator increases twice in each number.

2. Then, the formula is:

$a_n=\frac{3}{2^n}$

Where $n=1,2,3,4...$

3. The ratio of the geometric sequence is 2, and you can obtain it by dividing the term $\frac{a_{(n+1)}}{a_n}$
