I have no idea what im doing
1. what is the recursive rule for the sequence:
-7.4, -21.2, -35, -48.8, -62.6
A).an= an+1 - 13.8, where a1 = -7.4
B).an = an+1 + 13.8, where a1 = -7.4
C).an = an-1 - 13.8, where a1 = -7.4
D).an = an-1 + 13.8, where a1 = -7.4
my guess: D???
2. which answer is the explicit rule for the sequence 14.5, 11,7.5, 4, 0.5,...
A).an = 14.5 - 3.5n
B). an = 14.5 + 3.5n
C).an = 18 + 3.5n
D). an = 18 -3.5n
my guess: A??
3. which answer is the explicit rule for the sequence 3 ,8, 13, 18, 23
A).an = 2+5n
B).an = -2 +5n
C). an = -2 +5n
D. an = -2 - 5n
my guess: C??
