  1. Since the nth term is 4n, and 2916 = 4*729 It appears that there are 729 terms.

  3. Hmmm. I see I did make an error, since 4n would be

    4,8,12,16,....

    I have no idea how to get from 4 to 2916 in at most 35 terms, given the slow start. It does not appear exponential.

    I could of course insert any required number of terms, but the rule would be awkward.
