1. what is the recursive rule for the sequence?

−22.7, −18.4, −14.1, −9.8, −5.5, 
an=an+1+4.3 , where a1=−22.7

an=an−1−4.3 , where a1=−22.7

an=an−1+4.3 , where a1=−22.7

an=an+1−4.3 , where a1=−22.7

2. which answer is the explicit rule for the sequence 14.5, 11, 7.5, 4, 0.5,  ?

an=18−3.5n

an=18+3.5n

an=14.5−3.5n

an=14.5+3.5n

3.which answer is the explicit rule for the sequence 5, 11, 17, 23, 29  ?

an=1−6n

an=−1+6n

an=1+6n

an=−1−6n

4.the explicit rule for a sequence is given.

an=3n+1

what is the recursive rule for the sequence?

a1=3;  an=an−1+1

a1=4;  an=an−1+1

a1=1;  an=an−1+3

a1=4;  an=an−1+3

5. a supermarket finds that the number of boxes of a new cereal sold increases each week. in the first week, only 16 boxes of the cereal were sold. in the next week, 33 boxes of the cereal were sold and in the third week 50 boxes of the cereal were sold. the number of boxes of cereal sold each week represents an arithmetic sequence.

what is the explicit rule for the arithmetic sequence that defines the number of boxes of cereal sold in week n?

an=17n+1

an=17n−1

an=17n+33

an=17n−33

for all the .
