a(n) = 3/5
I'm sorry if this is not what you're expecting. But that equation says that
the value of the term doesn't depend on where it is in the sequence ...
on 'n' .
Every term is the same number. No matter what 'n' may be, the value of
a(n) is always 3/5.
The first five, fifty, five hundred, or five thousand terms are all 3/5 .
