1. 
what is the explicit rule for the arithmetic sequence that defines the number of boxes of cereal sold in week n shown in the photo?
A).an = 31n + 5
B). an = 31n - 5
C). an = 31n - 47
D). an = 31n + 47
2. the explicit rule for a sequence is given
an = -2n + 7
what is the recursive rule for the sequence?
A). a1 = 5; an = an-1 -2
B). a1 = 7; an = an-1 +2
C). a1 = 7; an = an-1 -2
D). a1 = -2; an = an-1 +7
