31.2,1,9,30,117,( ).
A.516 B.441 C.217 D.174
(2+1)*3=9
(1+9)*3=30
(9+30)*3=117
(30+117)*3=441
32.5,9,14,27,48,86,( ).
5+9+14-1=27
9+14+27-2=48
14+27+48-3=86
27+48+86-4=157
33.2,2,8,21,42,( ).
A.72 B.74 C.86 D.90
为二级等差数列
2,2,8,21,42
差为0,6,13,21
二级差6,7,8
则9+21+42=72
34.0,3,26,255,( ).
A.479 B.3124 C.2600 D.3104
1的1次方减1=0
2的2次方减1=3
3的3次方减1=26
4的4次方减1=255
5的5次方减1=3124
