STEP - BY - STEP EXPLANATION

What to find?

Determine whether the given series converge or diverge.

Given:

Step 1

Determine the common ratio.


\begin{gathered} (16)/(27)*(9)/(4)=(4)/(3) \\ \\ (4)/(9)*(3)/(1)=(4)/(3) \\ \\ (1)/(3)*(4)/(1)=(4)/(3) \end{gathered}

It is enough to see that it is a geometric series.

Step 2

List out the conditions for convergence /divergence of a geometric series.

• If the absolute value of the ,common ration, i.e, |r| is less than 1,, the the series ,converges,.

,

• If, |r| > 1, then the series, diverges.

Clearly, 4/3 > 1

This implies |r| >1, hence the series diverges.

ANSWER

The series diverges.

The series is geometric and the absolute value of the common ratio is greater than 1.
