(1) What is the 35th number? (2) What is the sum of the first 35 numbers? 相关知识点: 试题来源: 解析 (1)5.(2)137. (1) A group of four numbers "1, 3, 5, 7" is repeated in this number sequence. $35\div4=8\cdots\cdots3$, the 35th number should be the 3rd nu...
A group of four numbers "2, 4, 6, 8" is repeated in this sequence.24÷4=6. The 24th number should be the last in the 6th group and it should be "8". (2) 2 + 4 + 6 + 8 = 20. (3) The sum of the numbers of each group is 2+4+6+8=20, then the sum of the 24...

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 ...
解析 C根据数字可知,它们的规律是:2+2=4:4 × 2 =8:8+2 =10:10 ×2=20,第1、3、5项等位 置的数字加2等于后一位,第2、4、6项等位置 的数字乘以2等于后一位。 空格处为第6项, 应用前一项加2,也就是20+2=22。 故选C。 反馈 收藏 ...
The resulting DNA fragments are then ligated to technology-specific adaptor sequences, forming a fragment library. These adaptors may also have a unique molecular “barcode”, so each sample can be tagged with a unique DNA sequence. This...
both of these sequences have the same elements or members (1, 2, and 3), but they’re arranged in a different order—so they are, in fact, entirely different three-element long sequences. Of course, sequences don’t always have to have three elements—they can have any number of ele...
is achieved by writing code in a way that instructions are executed in a particular order. By structuring the code sequentially, each statement is executed after the previous one is completed. Control flow structures, such as loops and conditional statements, help control the sequence of ...
