1. -26, -6, 2, 4, 6, ( )
-26=-3的3次方+1；-6=-2的3次方+2；2=-1的3次方+3；4=0的3次方+4；6=1的3次方+5,所以最后一项是2的3次方+6=14
2. 0.003, 0.06, 0.9, 12, ( )
每项最后一个数字＋3然后乘以10得到后项,所以为150
3． 2, 7, 16, 39, 94, ( )
16＝7*2＋4
39＝16*2＋7
94＝39*2＋16
227＝94*2＋39 此题答案应为A227
4． 3, 7, 16, 41, (90 )
每两项的差为 4 9 25 49此数列为质数的平方
这个题你的答案也有问题
5． 5, 17, 21, 25, ( )
奇数数列 所以选C31
6. 80, 62, 45, 28, (9 )
80＝9的平方－1
62＝8的平方－2
45＝7的平方－4
28＝6的平方－8
9＝5的平方－16
