If I have a sequence e.g. $$a_{n+1} = \frac13 * (2a_n+\frac7{(a_n)^2})$$
and I have to calculate it for many iterations.. Is there an online tool which lets me choose a starting value and calculates the sequence for a certain maximum value of $n$ ? I searched around quite a bit, but did not find any tools that let me do this easily. Anyone knows a good option?
A very good solution for doing Math computations in Cloud is SageMathCloud.
