What is the recursive rule for the sequence? 4.4, 5.8, 7.2, 8.6, 10, … an=an+1+1.4 , where a1=4.4an=an−1−1.4 , where a1=4.4an=an−1+1.4 , where a1=4.4 an=an+1−1.4 , where a1=4.4

The next term is 1.4 larger than the one before it, so the appropriate choice is

_____

However, the description

also correctly describes the relationship between a1 and a2, for example. While this equation is technically correct, it is less useful to work with, so is probably not the expected answer.

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
