Hello:
0,4,16,40,80, （140 ）
Observe the regular gradual increase of the number, focusing on the former minus the latter
A new sequence is generated by subtracting the preceding term from the following term
4,12,24,40；
There is no obvious law, and the number is still increasing gently, still consider the former minus the latter
The new sequence of the preceding minus the following:
8,12,16, that is, the arithmetic sequence with tolerance of 4, the next term should be 20, which is reduced to:
4,12,24,40；20+40=60；
Re reduction: 0 4 16 40 80,80 + 60 = 140
