Consider the following series. 1 4 + 1 8 + 1 12 + 1 16 + 1 20 Determine whether the series is convergent or divergent. Justify y

patriot [66]

Answer:

The series diverges

Step-by-step explanation:

First, let's find the sequence:

$4, 8, 12, 16, 20,...,$

As we can see, they are multiples of 4, so one possible sequence is:

$4,8,12,16,20,...,=4n\hspace{8};\hspace{3}n\in Z$

Hence, we can represent the series as:

$$$\sum_{n=1}^{\infty} 4n$

Let's use the zero test which states:

$$$\Sigma a_n$$\\Diverges\hspace{3}if\\\\ \lim_{n \to \infty} a_n \neq 0$

So:

$\lim_{n \to \infty} 4n= 4 \lim_{n \to \infty} n\\ \\ \lim_{n \to \infty} n=\infty\\ \\4\infty= \infty\\\\Hence\\\\ \lim_{n \to \infty} 4n=\infty$

Therefore, by the zero test, the series diverges

Help would be good i dont know how to do this

$\frac{x^2-4x-32}{x^2+7x+12}=\frac{x^2+4x-8x-32}{x^2+4x+3x+12}=\frac{x(x+4)-8(x+4)}{x(x+4)+3(x+4)}=\\\frac{(x+4)(x-8)}{(x+4)(x+3)}=\frac{x-8}{x+3}$
