The explicit formula would be 
The sequence is geometric, since we are multiplying by a constant each time to get the next term. The common ratio, r, is 3. The first term, g₁, is 5. An explicit formula for a geometric sequence is given by
Using our information, we have

Answer:
This expression is missing operators and has no meaning. If you add commas to separate the expressions, and equals signs where appropriate, then assistance can be given.
Assuming that the blank spaces between terms are meant to be plus signs, then the final answer would be 9x.
Step-by-step explanation:
To make some sense of this, let's assume that the operator between "5x-4" and "6x-23" is a plus sign, and that the minus sign on "-2x + 33" is itself the operator there. If that is the case then this can be solved by simply grouping like terms and summing them up:
group like terms:
The numbers with no coefficient add up to zero:
Leaving us with the final answer.
The region(s) represent the intersection of Set A and Set B (A∩B) is region II
<h3>How to determine which region(s) represent the intersection of Set A and Set B (A∩B)?</h3>The complete question is added as an attachment
The universal set is given as:
Set U
While the subsets are:
- Set A
- Set B
The intersection of set A and set B is the region that is common in set A and set B
From the attached figure, we have the region that is common in set A and set B to be region II
This means that
The intersection of set A and set B is the region II
Hence, the region(s) represent the intersection of Set A and Set B (A∩B) is region II
