Using an arithmetic sequence, the formula for the nth term is given by:
-------------------------------
- In an arithmetic sequence, the difference between consecutive terms is always the same, and it is called common difference d.
- The nth term is given by:
- In which
is the first term.
In the recursive sequence, we have that:
Then
And so on...
The sequence is: {-4, -6, -8,...}
Which is an arithmetic sequence with and
, thus, the definition for the nth term is:
