    Algebra1 CCSS uses f(n), f(n+1) notation for sequences, but there is a concern that students will “evaluate” f(n+1) as f(x+1). I would appreciate feedback.

    Hi Lane, could you explain a bit more? Maybe give an example of what people are concerned that students might do.

    Interestingly enough, the f(n) concern turned out to be a paper tiger. The real problem is that lots of people do not realize a sequence is a function. The terminology input-output is not universally understood, and those worried about confusion students might have appear to have been confused themselves. Can I thank you, once again Dr. McCallum, for the beautiful job you have done with these standards?
