首先计算相邻项的差值:6-3=3,11-6=5,20-11=9,37-20=17。这些差值构成新的数列3,5,9,17。观察差值的差值:5-3=2,9-5=4,17-9=8,可以看出这里是公比为2的等比数列。下一个二次差应为16(8×2),则下一个一次差为17+16=33,因此空缺数为37+33=70。验证后续差值:下一个二次差32(16×2),对应一次...

Find the missing number in the sequence：3,6,11,20,37，（70 ），135.Answer:( 70).观察可以发现6=3×2-0；11=6×2-1；20=11×2-2；37=20×2-3；即每一个数是它前面的数乘2再减去比它的项数少1的自然数，由此得出答案．解：因为6=3×2-0；11=6×2-1；20=11×2-2；37=...
我这样算：3×2-0=6 6×2-1=11 11×2-2=20 20×2-3=37 37×2-4=70 70×2-5=135 答案绝对是70，望采纳！
