(1)选D 每个数字与前个数字的差为92,38,16,6;
它们之间的差又为54(2*27),22(2*11),
10(2*5),类推下一个数字为1.
(2)选D (1+5)/(1+8)=2/3,(2+13)/(3+21)=5/8,依此类推
(5+34)/(8+55)=13/21,所以答案为34/55
(3)选C 3*3+5=14 5*5-5=20 7*7+5=54 9*9-5=76
所以:11*11+5=126
(4)选B 类推1的6次方、2的5次方.6的1次方
(5)选B 2*2+3的平方=13;3*2+13的平方=175;
那么:13*2+175的平方=30651.
(6)选A 3*7-5=16;7*16-5=107;所以:16*107-5=1707
