The third term in an arithmetic sequence is 3, and the common difference between each term is 4. Write a recursive formula for the sequence.
A
an = 4an – 1 where a3 = 3B
an = an – 1 + 4 where a3 = 3C
an = an – 1 + 4 where a1 = 3D
an = 3 + (n – 1) · 4 where a3 = 32

Identify the recursive formula for the following sequence: 8, 26, 80, 242, . . .
A
an = an – 1 + 18 where a1 = 8B
an = 3an – 1 + 2 where a1 = 8C
an = 4an – 1 – 6 where a1 = 242D
an = 8 + (n–1) · 18 where a1 = 183
