#### Answer

The series diverges.

#### Work Step by Step

Using the test for divergence that is stated in page 753 of the textbook we will take the limit of the corresponding sequence to the given series. Meaning, we will solve: $\lim\limits_{n \to \infty} \frac{2+n}{1-2n}$, to solve this we take the highest power of n from the numerator and the denominator which gives us the following:
$\lim\limits_{n \to \infty} \frac{\frac{2}{n}+1}{\frac{1}{n}-2 }$ and taking n towards $\infty$ the fraction with n at denominator become zero and what remains is: $\frac{-1}{2}$ $\ne$ 0 . Thus by test for divergence our series diverges.
