Answer:
21.204
Step-by-step explanation:
The explicit formula for the geometric sequence
is

Step-by-step explanation:
The formula of the nth term of a geometric sequence is
, where:
- a is the first term of the sequence
- r is the common ratio between the consecutive terms
The geometric sequence of
is 6 , -2 ,
,
, 
∵
= 6
∵ 
∵
= -2
∴ 
- Divide both term by 2 to simplify it
∴ 
∵ 
- Substitute the value of
and r in the rule above
∴ 
The explicit formula for the geometric sequence
is
