1. what are the first five terms of the sequence given by the formula an = 5n + 1?
1, 5, 9, 13, 17
6, 11, 16, 21, 26
5, 10, 15, 20, 25
5, 6, 7, 8, 9
2. write a recursive definition for the sequence 8, 6, 4, 2, …
a1 = 8; an= an–1 − 2
a1 = 2; an= an–1 + 6
a1 = 8; an= an–1 + 2
a1 = 2; an= an–1 + 8
3. write an explicit definition for the sequence −2, 1, 4, 7, …
an = –2 + 3n
an = –2 + (n – 3)
an = –2 + (n – 3)
an = –2 + 3 (n – 1)
