Find the pattern of the following sequence and determine the next few terms:

2, 10, 12, 38, 42, 52, 56, 142, 150, 170

Charlie and I each showed a solution.  Maybe there are addtional potential solutions as well.  Though each method accurately reproduces the above 10 terms of the sequence, Charlie's solution has the simpler algorithm and is therefore the better of the two, in my opinion. 

About a year ago, there were some postings regarding sequences that complained that not enough terms were shown, and therefore an infinite number of possible solutions might exist.  (I think about 5 or 6 terms were shown in that problem).  I'm surprised that 10 terms were not enough to lead to a unique solution.  In any event, I had fun working out a solution, so I'm not disappointed in the least.
