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...
百度试题 结果1 题目Finish the number in the sequence 1, 1, 2, 2, 3, 4, 4, 8, 5, . 相关知识点: 试题来源: 解析 16 分成奇数项数列和偶数项数列,奇数项分别为1,2,3,4,5…偶数项分别为1,2,4,8,___. 所以横线上应该填16.反馈 收藏 ...
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!
34+55=89 4. Calculate the Next Number: - To find the next number after 89, we sum the ninth (55) and tenth (89) numbers: 55+89=144 5. Conclusion: The next number in the sequence is 144. Final Answer:The next number in the sequence is 144. Show More ...
Find the missing number in the sequence:3,6,11,20,37,___,135.Answer:___. 答案 因为6=3×2-0;11=6×2-1;20=11×2-2;37=20×2-3;所以下个数应该为:37×2-4=70;验证:70×2-5=135正好是最后一个数;故答案为:70 结果三 题目 Find the missing number in the sequence:3,6,11,20,...
A. 9 B. 10 C. 11 D. 12 相关知识点: 试题来源: 解析 B。本题考查数字序列。这个序列是连续的偶数,2、4、6、8,下一个偶数是 10。A 选项“9”是奇数,不符合序列规律。C 选项“11”也是奇数。D 选项“12”不是紧挨着 8 的下一个数。反馈 收藏 ...
