May I ask for how to prepare for real analysis exams? I am just having a tough time in real analysis. I got my mid term yesterday and it is only 45/100..... Any skills to revise real analysis?
because x represents n And n represents the position of the term in the sequence for ex. the first term has n=1, the second term has n=2, the 10th term has n=10 and so on. you can't say n is -1 because there's no such position therefore n=x which is greater than or equal to 1.
