"WebMar 26, 2016 · A convergent sequence has a limit — that is, it approaches a real number. A divergent sequence doesn’t have a limit. Here’s an example of a convergent sequence: This sequence approaches 0, so: Thus, this sequence converges to 0. Here’s another convergent sequence: This time, the sequence approaches 8 from above and below, so: " - How to show if a series diverges or converges

WebWhile it is true that the terms in 1/x are reducing (and you'd naturally think the series converges), the terms don't get smaller quick enough and hence, each time you add the next number in a series, the sum keeps increasing. However, in case of 1/x 2, the terms decrease rapidly (much faster than 1/x) and hence, that series converges. das horror clownWebAs a reminder...
