Find the nth term of 1/3+4/243+1/243+16/19,683?

[GiannaMe'arah]

by simplifying the denominator, 1/3 + 4/3^5 + 9/3^7 + 16/3^9

Cant find the nth term. i am assuming there is something wrong with the given. i suppose 1/3 should be 1/3^3. If so, then the nth term is n^2/3^(2n+1)

thanks.. :)

In your title you wrote 1/3+4/243+1/243+16/19,683?

Was the third term a typo? If it's how you write it in your post, then yeah, I think the first should be 1/3⁵ instead.
