Answer:
Step-by-step explanation:
First, as you can see, the sequence is alternating its sign everytime, so you can deduce this term:
The sequence start from 3, and the following terms are the product between 3 and . Take a look:
For n=1
For n=2
And so on...
Let's verify the formula including all terms:
Since the sequence start from 3, we must change the 3 for -3. Because is always negative for the first term:
For n=1
For n=2
For n=3
For n=4
So, one possible sequence is:
And the serie would be given by:
