找规律填数:①1,1,2,3,8,(),21,( ) ②4,9,( ),43,( ),185①1,1,2,3,8,(),21,( )②4,9,( ),43,( ),185
找规律填数:①1,1,2,3,8,(),21,( ) ②4,9,( ),43,( ),185
①1,1,2,3,8,(),21,( )
②4,9,( ),43,( ),185

找规律填数:①1,1,2,3,8,(),21,( ) ②4,9,( ),43,( ),185①1,1,2,3,8,(),21,( )②4,9,( ),43,( ),185
①1,1,2,3,8,( ),21,( ):
②4,9,( 20 ),43,( 90 ),185:
规律:4*2+1=9
9*2+2=20
20*2+3=43
43*2+4=90
90*2+5=185
所以4,9,(20),43,(90),185
