1,2,3,7,46,
0,1,3,8,22,63,
1,1,2,6,12 (1*2,2*3,3*4=12)
1,3,5,7,9,13,15,17(奇数分组吧)
1,1,1,2,4,7,13,25 (4*2-1,7*2-1,13*2-1=25)
2,3,10,15,26,39 偶数项与其前一项的比例为2:3;
1,10,31,70,133,226 后项减前项得一新数列:9,21,39,63,此新数列继续减得:12,18,24,可以看出是各项加6的等差数列,返回去就是...30,...93,...226
1,2,3,7,46,2112 (2*2-1,3*3-2,7*7-3,46*46-4)
0,1,3,8,22,63,183 (1*3-0,3*3-1,8*3-2,22*3-3,63*3-4)
