12 and 15.

Answer 3

You're welcome.

Answer 4

There are two types of sequences: arithmetic and geometric.
In an arithmetic sequence, there is always the same difference between any to consecutive terms.
In a geometric sequence, there is always the same ratio between any two consecutive terms.

Answer 5

I'd rephrase that as "two types of sequences are arithmetic and geometric" as there are other types of sequences...
