如果本题有什么不明白可以追问,还有2道,多谢啦在哪啊1.02,1.12,1.32,1.62(),2.52在发1.02,1.12,1.32,1.62(2.02),2.52

1.12-1.02=0.1;
1.32-1.12=0.2;
1.62-1.32=0.3;
()-1.62=0.4;
∴()=2.02;
2.52-2.02=-0.5;8.5,16.9,33.7,67.3( )268.9麻烦了8.5,16.9,33.7,67.3(134.5 )268.9

16.9-8.5=8.4;
33.7-16.9=16.8;16.8=8.4×2;
67.3-33.7=33.6;16.8×2=33.6;
()-67.3=67.2; 33.6×2=67.2;
∴()=134.5;
268.9-134.5=134.4;67.2×2=134.4;
