The general term of a sequence is given. In each case find the first four terms,
the 10th term, and the 15th term.
5. an = n² – 2n 6. an = 1 7. an = n +1 8. an = ( - )"-
Find the first five terms of these recursively defined sequences.
9. a1 = 2, an+1 = 4an - 3 10. a1 = -3, an+1 = 2an - 5
11. a1 = 8, an+1 = žan +2 12. a1 = 3, a2 = 3, an+1 = an - an-1
