we get questions like these a lot. someone had posted something similar, and just like this one, we couldnt find a pattern. So using the fact that we never know how to the tail of a sequence acts, i made up a tail, and found a formula. if its correct or not, we will never know...but it does work for the first couple of numbers.

ok, the formula is: \[\frac{3}{10}(3)^n+\frac{5}{504}(2)^n\frac{335}{9}(1)^n+\frac{1107}{40}(2)^n\frac{101}{36}(4)^n+\frac{9}{14}(5)^n\] for n = 1,2,3...,6 it equals those numbers up top. http://www.wolframalpha.com/input/?i=%E2%88%923%2F10%28%E2%88%923%29^n%2B5%2F504%28%E2%88%922%29^n%E2%88%92335%2F9%281%29^n%2B1107%2F40%282%29^n%E2%88%92101%2F36%284%29^n%2B9%2F14%285%29^n%2C+n+%3D+6 where you type in the equation, if you scroll to the right you can change the value of n to make sure it works.
