找规律:(1):3,5,8,12,( ) (2):20,34找规律:(1):3,5,8,12,( )(2):20,34,55,83,( )
找规律:(1):3,5,8,12,( ) (2):20,34
找规律:(1):3,5,8,12,( )
(2):20,34,55,83,( )

找规律:(1):3,5,8,12,( ) (2):20,34找规律:(1):3,5,8,12,( )(2):20,34,55,83,( )
17 118

1 20
2 118

(1):3,5,8,12,( 16 )
(2):20,34,55,83,( 118 )

3,5,8,12 分别间隔2,3,4,所以最后一个间隔是5,12+5=17;
20,34,55,83分别间隔14,21,28即2乘7,3乘7,4乘7,所以最后一个间隔是5乘以7,即35+83=118
