9.25 − 4.5q = -19.37 − 15.1q
Natalija [7]

Step 1: Simplify both sides of the equation.

9.25−4.5q=−19.37−15.1q

9.25+−4.5q=−19.37+−15.1q

−4.5q+9.25=−15.1q−19.37

Step 2: Add 15.1q to both sides.

−4.5q+9.25+15.1q=−15.1q−19.37+15.1q

10.6q+9.25=−19.37

Step 3: Subtract 9.25 from both sides.

10.6q+9.25−9.25=−19.37−9.25

10.6q=−28.62

Step 4: Divide both sides by 10.6.

\frac{10.6q}{10.6} =  \frac{-28.62}{10.6}

q=−2.7

Please and thankyou (:
den301095 [7]

Let's evaluate the ratio test:

\dfrac{a_n}{a_{n-1}}=\dfrac{3^{n+1}}{3n+1}\cdot\dfrac{3(n-1)+1}{3^n}=\dfrac{3\cdot3^n}{3n+1}\cdot\dfrac{3n-2}{3^n} = \dfrac{9n-6}{3n+1}

The limit as n \to\infty of this quantity is 3, which is more than 1. So, the series diverges.
