surely you can do A. A simple arithmetic progression.
I suspect B is supposed to be
9,-3,1,-1/3,...
a simple geometric sequence.
You have handy formulas for these things.
thank you Steve for helping me out.
Accurately classify the sequence and then create a corresponding explicit and recursive formula for finding the nth terms of each sequence.
A. 32, 30, 28, 26,.....
B. 9,-3, 1, - _1 .......
