Sequences part 2

Hi again,

Looking more at sequences, I have some sequences that start with ID 1, incrementing each record by 1.
So I have e.g. 1 Spain 2. Germany 3. France 4. Ireland 5. Norway
Now I want to insert more countries, between France and Ireland. And also alter the increment. That latter part might be easy as I understood it? But can I achieve this:
1 Spain 2. Germany 3. France 4. Greece 5. Latvia 6. Cyprus 7. Ireland 8. Norway
That is inserting records in the middle of the records, maybe even
1 Spain 2. Germany 3. France 4. Greece 5. Ireland 6. Norway 14. Latvia 24. Cyprus
