At present, in many public institutions and state-owned enterprise examinations, there will be some questions about digital reasoning. What is a digital reasoning question is to give some number sequences and deduce the number of the next number through the laws of the previous number. This type of question is both a difficulty and a pain point for most students. This type of question is mainly to examine the examinee's sensitivity to some numbers or common sequences of numbers, and then solve the answer by mastering the skills. This type of question is mainly to examine the examinee's sensitivity to some numbers or common sequences of numbers, and then try to find the rules through the mastered skills. In fact, if you master the skills of digital reasoning, you can win this module faster and more accurately. In this article, let's learn some tricks in digital reasoning.
1. What is digital sensitivity?
The sensitivity of numbers, as its name implies, is to see that a number can associate some relationships with it. For example, 50 is an even number and a composite number, which can be split into: 25+25; 2×25;;... It is the ability to associate numbers.
2. What is sequence sensitivity?
Be familiar with some commonly used basic number sequences. For example:
Odd columns: 1, 3, 5, 7, 9, 11
Even number column: 2, 4, 6, 8, 10, 12
Prime number column: 2, 3, 5, 7, 11, 13
Composite columns: 4, 6, 8, 9, 10, 12
Sum sequence: 1, 2, 3, 5, 8, 13
Square sequence: 1, 4, 9, 16, 25, 36
Cubic series: 1, 8, 27, 64125216
Cyclic sequence: 1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3, 2, 3
3. Method application
[Example 1] - 4, 0, 6, 14, (), 33
A.20 B.21 C.23 D.25
[Answer] C
[Analysis] The difference is 4, 6, 8, 9, 10, and 14+9=(23) should be filled.
[Example 2] 3, 5, 7, 11, 17, (27), 43
A.25 B.26 C.27 D.28
[Answer] A
[Analysis] The first item+the second item - 1=the third item, and so on, 11+17-1=(27), 17+(27) - 1=43.
Method application: The sequence of numbers is basically monotonous, the maximum amplitude of two terms is about twice, and the difference by difference/sum can be given priority.
[Example 3] 5, 10, 26, 65, ().
A.89 B.125 C.153 D.170
[Answer] D
Method application: If there is an obvious multiple number sequence in the number sequence, you can directly consider using the multiple number sequence.
[Example 4] 2, 3, 7, 22, (155), 3411
A.155 B.165 C.175 D.185
[Answer] A
[Analysis]: the first item × the second item+1=the third item, and so on: 7 × 22+1=(155),, 22 × (155)+1=3411
Method application: The sequence of numbers is basically monotonous, and the amplitude of the maximum two terms is more than 3 times, or even greater, so the priority can be given to multiplication/quotient.
Through the study of the four exercise questions above, we will find that the questions of digital reasoning have certain characteristics, and can be solved according to certain methods and tips. Therefore, we need everyone to learn and use our various problem-solving methods flexibly. Don't study blindly. The effect of self-study is poor. For the exam, we must find effective methods and techniques to prepare lessons scientifically, otherwise it will be useless. It is suggested that all examinees should first master the basics of numerical reasoning and then understand the key points of problem-solving skills. Finally, a large number of questions are written, and they are skilled in heart. In this way, the problem of digital reasoning can be solved effectively when corresponding problems are encountered later.
