I believe the next number if 14, since the sequence looks like the two digit primes starting at 11 (11,13,17,19,23,29,31,37,41, ...), but with their digits reversed.

I can see that the 1st, 3rd etc. numbers multiply by 3 each time. I can see that the 2nd, 4th etc. numbers subtract 2 each time. Which would give a continuation to the series: 2 9 6 7 18 5 54 3 162 1 486... with 54 the for the requested 7th term. However, there are an infinite number of formulae for the individual terms which would give any value to the 7th term!!!

Ben is correct. The next number in the sequence is 14.

I tried to figure this problem out and it is very hard. I came up with many solutions. I believe it is 23.
