You can try. It is not a straight geometric nor a straight arithmetic series.
the columns are differences
geometric ratios
1.5 0.22222222 6.5 0.76923077 0.3
There is no real distinguishable arithmetic pattern
6 3 -10 28 -60 102
9 -7 18 -32 42 102
2 11 -14 10 144
13 -3 -4 154
10 -7 150
3 143
146
7th term could be 146
