The explicit rule for a sequence is given.
an=1/2(4/3)^n−1
Enter the recursive rule for the geometric sequence.

a1 =
an =

The recursive rule for the geometric sequence is given by   and this can be determined by finding the geometric ratio 'r'.

Given :

Geometric Sequence  --    

Now, substitute the value of n = 1 in the above given geometric sequence.

Now, substitute the value of n = 2 in the given geometric sequence.

To determine the value of r which is the geometric ratio use the below calculation:

So, the recursive rule for the geometric sequence is given by:

= 1/2

= *

Step-by-step explanation:

plug 1 into =1/2(4/3)^n−1  to find

=1/2(4/3)^1−1

= 1/2 (4/3)^0

= 1/2 * 1

= 1/2

= * r where r is the ratio

since (4/3) is being taken to an exponent, (4/3) is r

= *
