Discuss convergence or divergence of a series.

Hey! Before discussing a series’ convergence or divergence, you have to know what convergence and divergence are.

Now Take a look into what the convergence or divergence of a series is, Firstly take a look into what is the convergence or divergence of a series.

Convergence of a series

As you Know series is the sum of a sequence of numbers, if the sum of a series approaches some finite value then it is known as convergence of series. convergence of a series is the series that approaches a set limit is known as convergence of a series. It is used to describe the phenomenon of the futures price and the cash price.

Example:

• Traders refer to convergence as a way to describe the price action of a futures contract

Divergence of a series

If the sum of a series approaches some infinite value then it is known as the Divergence of series. Divergence of a series is the series that does not approach a set limit is known as Divergence of a series. It can be either positive or negative.

Example:

• positive divergence occurs when a stock is nearing a low but its indicators start to rally. 
• negative divergence happens when prices go higher while the indicator signals a new low

In the end, We have concluded that if the sum of a series approaches some finite value then it is known as convergence and if the sum of a series does not approach some finite value then it is known as divergence.
