1. Geometric sequence

2. ;

3.

Step-by-step explanation:

The sequence is Geometric.

For the sequence to be Geometric , then there must exist a common ratio

check:

6/-2 = -18/6 = 54/-18 = -3

The recursive formula for the sequence is :

;

To find the explicit formula:

The formula for the nth term of a Geometric sequence is given as :

where :

a = first term

r = common ratio

so , substituting the values into the formula , we have :

therefore : the explicit formula =

is there a picture

the bolded word " farsighted" could be replaced with visionary.
