Check out these two expressions

The two expressions are approximately equal. Not exactly equal. But approximately. Till 7 places of decimals or more. Also the number of terms in LHS and RHS in both are odd number of terms. Not even number. In case the number of terms are even number then it gives some other value.
Again, many readers of my blog may be confused. I am sorry for that. Perhaps I need to write a paper on this. I shall think about it.

In total I made three approximate expressions. I am putting all the three expressions here for the help of the reader.

Have a nice day, my dear readers.
