Use the ratio test to determine whether the series is convergent or divergent.

Kitty [74]

Answer:

Divergent

Step-by-step explanation:

Given series has general term as

$\frac{2^n}{n^2}$

n+1 th term = $\frac{2^(n+1)}{(n+1)^2}$

WE have to check whether this series converges or diverges

Let us use ratio test

Ratio of n+1 th term to nth term

= $\frac{2n^2}{(n+1)^2} =\frac{2}{(1+\frac{1}{n} }^2$

by dividing numerator and denominator by n square

Take limits as n tends to infinity

The ratio tends to 2

Since ratio >2, the series diverges
