How can I select rows in reverse order in MySQL?

For example, I have a table with 12 rows (fields: id,location), I want to select the 4th row before a row with id = 6. I.e., the wanted row will have id = 'not necessarily 2', but there is a condition - where table.location='some_location'.

What should the content of request to MySQL be like?

Here is a solution!

Some example (I checked drodil's suggestion):

mysql> select * from subscrs where id < 100000 order by id desc limit 4;
+-------+--------+-----------+-------+
| uid   | subscr | event     | id    |
+-------+--------+-----------+-------+
|  5307 |   5123 | feed_news | 99999 |
| 25985 |   5211 | feed_news | 99998 |
| 15123 |    130 | feed_news | 99997 |
| 28368 |  19497 | feed_news | 99996 |
+-------+--------+-----------+-------+
