Question 925652: . Which is the iterative rule for the sequence: 2, 9, 16, 23, 30, …?
(Points : 1)
a. an = –5 – 7n
b. an = 2 – 7n
c. an = 2 + 7n
d. an = –5 + 7n

You can put this solution on YOUR website!
the sequence: 2, 9, 16, 23, 30, …
the difference between 2 and 9 is 7, between 9 and16is 7,between 16 and23is 7, as between 23 and30 as well is 7
so, 2=7n-5, then your answer is:
d. a%5Bn%5D+=+-5+%2B+7n
