Question

Natalia is writing a recursiye formula to represent the

Answer 1

Answer:

3/2

Step-by-step explanation:

3/2 is the value

Answer 2

Answer:

1.5

Step-by-step explanation:

As the common difference is not same for all terms, the given sequence is a geometric sequence

the standard formula for a geometric sequence is:

$a_n=a_1r^{n-1}$

The formula to calculate common ratio is:

$r = \frac{a_n}{a_{n-1}}$

Dividing the term by previous term

So,

r = 12/8 = 18/12 = 27/18 = 1.5

The value for common ratio will be:

1.5 ..
