HP 38G: Better than Prime for some Sequences using the built in Sequence App

The performance of the Prime is disappointing.

There is a reason: The implementation with the TT routine evaluates each element of the sequence from scratch while the sequence app recurses on the previous results. Maybe storing the previous values in a list instead of performing a recursive call will give better run times. This of course makes the calls to TT not independent from each other.
