$\"\"$

If a sequence $\"\"$ is convergent, then there exist $\"\"$ , where $\"\"$ is a constant.

The sequence is $\"\"$ .

By the defination $\"\"$ .

$\"\"$

The product which is in the braces is a product of infinetely many terms each of which

is greater than $\"\"$ .

Therefore $\"\"$ .

$\"\"$ .

Thus, the sequence diverges.
