Mình sẽ nói kết quả sau khi giải thích :

1 , 3 , 6 , 10 , 15 , 21 , 28 , ...

1 + 2 = 3 + 3 = 6 + 4 = 10 + 5 = 15 + 6 = 21 + 7 = 28 ...

Là cộng thứ tự tăng dần .

Vậy , muốn tìm số thứ 23 , mình sẽ làm ngay !

1 , 3 , 6 , 10 , 15 , 21 , 28 , 36 , 45 , 50 , 61 , 73 , 86 , 100 , 115 , 121 , 138 , 156 , 175 , 195 , 216 , 238 , 261 .

Số 261 là số thứ 23 .

Vậy số thỏa mãn đề bài là 261 .

Vì thế, 4 số hạng đầu tiên của dãy số là: 6, 3, 10, 5. Tìm số hạng thứ 100 của dãy số. Given the sequence with the first term is 6, the following consecutive terms are defined as follows: if a term with a value of t is even, then the next term has a value of ½ t; If a term with a value of s is odd, the next term has a value of 3s + 1. Therefore, the first 4 terms of the sequence are: 6, 3, 10, 5. Find the 100th term of the sequence.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the following questions.

The three phases of the human memory are the sensory memory, the short-term memory, and the long-term memory. This division of the memory into phases is based on the length of time of the memory.

Sensory memory is instantaneous memory. It is an image or memory that enters your mind only for a short period of time; it comes and goes in under a second. The memory will not last longer than that unless the information enters the short-term memory.

Information can be held in the short-term memory for about twenty seconds or as long as you are actively using it. If you repeat a fact to yourself, that fact will stay in your short-term memory as long as you keep repeating it. Once you stop repeating it, either it is forgotten or it moves into long term memory.

Long-term memory is the huge memory tank that can hold ideas and images for years and years. Information can be added to your long-term memory when you actively try to put it there through memorization or when an idea or image enters your mind on its own.

Question:All of the following are true about long-term memory EXCEPT that________.

 

A.  it has a very large capacity

B.  memorization is the only way that information can get there

C.  it can hold information for a long time

D.  it is possible to put information into it through memorization
