SOLUTION: Write a formula for the nth term for the sequence below:
2/5, 4/6, 6/7, 8/8, ...
I sort of know how to set it up. Just having a problem finding the difference.
a(n)= 2/5*

a(n)= 2/5* [?] ^(n-1)
thanks :) Answer by LinnW(1048) (Show Source):
You can put this solution on YOUR website! beginning with n = 1, the first term
the first element is 2n/(n+4)
so the first element is 2(1)/(1+4) = 2/5
The nth will follow the formula 2n/(n+4).
