Help please

Step 1

Consider the given series:

Step 2

Now, further

Since,

Step 3

It is known that, the series ∑ is divergent by p-series test, since here p=1/2, which is less than 1, hence divergent.

Now, by **limit comparison test:** for two series an and bn such that an ≤ bn then if ∑an is divergent then so is ∑bn...
