SOLUTION:
Case: Sequences
Method:
3, 12, 48, 192,...
Step1:
The sequence is increasing exponentially
Type: Geometric/Exponential Sequence
Step 2:
The Explicit rule is gotten from the formula:
[tex]a_n=ar^{n-1}[/tex]
a= 3,
r= (12/3)
r= 4.
The rule, therefore:
[tex]a_n=3(4)^{n-1}[/tex]
Final answer:
Type: Geometric sequence
Explicit rule
[tex]a_n=3(4)^{n-1}[/tex]
