Determine if the following series is convergent or divergent by using Radio Test.

171_Determine series is convergent or divergent by Radio Test 1.png

Solution

With this first illustration let's be a little careful and ensure that we have everything down correctly.  Now Here are the series terms an.

an = (-10)n/42n+1 (n+1)

Remind that to compute an+1 all that there is a requirement to do is substitute n+1 for all the n's in an.

an+1 = (-10)n+1/ 42(n+1)+1 ((n+1)+1

= (-10)n+1/ 42n+3 (n+2)

Now, to illustrate L we will use,

As this will be a little easier while dealing with fractions like we've got here.  Thus,

Thus, L<1 and so by the Ratio Test the series converges absolutely and therefore will converge.
