Huawei interview topic mathematics
There are two solutions and two answers to this question:

1, the answer is 1.

1=4, 2=8, 3=24. The answer to this question is written at the beginning, which is 4= 1.

2. The answer is 96

1=4, 4×2=8,? 8×3=24,? 24×4=96 is the result of the previous formula multiplied by the serial number of the following formula, which is the answer of the formula, so the result of 4 is 4× 24 = 96.

This is a difficult problem.

Puzzles can examine the respondent's attention, observation, logical thinking, imagination and memory in any form. The topic is reasonable, informative and entertaining, and the form of the topic is not limited.

Extended data:

If 1=4, 2=8 and 3=24, then 4= is a mystery.

The application of intelligence questions has become more and more extensive, and many companies regard it as an interview topic, and there are similar questions in the civil service examination.

The way to solve the puzzle:

1, exclusion method

Exclude some irrelevant problems first, determine the determinable problems first, and narrow the unknown range as much as possible, so as to facilitate the analysis and solution of the problems. This way of thinking is very useful in our work and life.

2. Recursive method

Through the layer-by-layer analysis of the known conditions, each step can be ensured to be accurate. There may be several "branches", so we should start with a simple one based on the principle of easy before difficult.

3. Backward extrapolation method

Start with the final result of the question and advance step by step until you find the answer to the question. Some problems are easy to solve in this way, but difficult to solve in other ways.

4. Hypothetical method

For a given problem, first make one or several assumptions, and then analyze it according to the given conditions. If there is a contradiction with the conditions given in the title, it means that the assumption is wrong, and then make another assumption or other assumptions. If there are only two possible outcomes, then the problem has been solved. In the history of science, "hypothesis" has played a great role.

5. Calculation method

Some problems must be solved by calculation. It should be noted that questions in intelligence tests often contain implicit conditions, and sometimes the numbers given are useless.

6. Analytical method

This is the most basic method. Analytical methods are often used in various methods. It can be said that the analytical ability is the embodiment of a person's intelligence level. Analytical ability is not only innate, but also largely depends on acquired training. We should form the good habit of analyzing objective things.

7. Drawing method

According to the known conditions in the problem, it is helpful to draw pictures in an appropriate way. Some problems will be very helpless before painting, and will be clear at a glance after painting.

8. Integrated approach

In fact, many problems have to be solved in several different ways. The so-called comprehensive method is to integrate various methods (including methods other than the above methods) to solve some problems.
