V125BC [204]3 years ago
3 0

Answer:

The progression is Option A. convergent.

Step-by-step explanation:

The given series is( -\frac{8}{5}+\frac{32}{25}-\frac{128}{125}+......)

=(-\frac{8}{5})(1-\frac{4}{5}+(\frac{4}{5})^{2}-.....)

Now we can write this series as \sum_{n=0}^{n=\oe}(-\frac{8}{5})(-\frac{4}{5})^{n}

In this expression common ration is 4/5= 0.8

As we know that in geometric progression if common factor is less than one then the progression converges.

Therefore we can say that this progression is convergent.
