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:


a_n=ar^(n-1)

a= 3,

r= (12/3)

r= 4.

The rule, therefore:


a_n=3(4)^(n-1)

Final answer:

Type: Geometric sequence

Explicit rule


a_n=3(4)^(n-1)
