(a) What is a sequence?(b) What does it mean to say that $ \lim_{n \to \infty} a_n = 8? $(c) What does it mean to say that $ \lim_{n \to \infty} a_n = \infty? $
(a) What is a convergent sequence? Give two examples.(b) What is a divergent sequence? Give two examples.
List the first five terms of the sequence.$ a_n = \frac {2^n}{2n + 1} $
.List the first five terms of the sequence.$ a_n = \frac {n^2 - 1}{n^2 + 1} $
List the first five terms of the sequence.$ a_n = \frac {(-1)^{n-1}}{5^n} $
List the first five terms of the sequence.$$ a_n = \cos {n \pi}{2} $$
