Problems from childhood, which were solved with his grandfather when he was alive

Addressing numbers problems It is necessary not only for a student who knows the basics of mathematics, but also for a fully adult person. After all, such work is a real exercise for the mind. And sometimes adults who are mired in routine need such a shake-up much more than children who are already every day learning and constantly learning something new.

So today's editorial office. "Site" will offer several tasks where it will be necessary not so much to count as to show ingenuity. Try to turn on your ingenuity to the maximum to solve these trick problems.

1. In the first task, you need to understand the sequence of numbers in order to continue it. Try to understand what the pattern is and specify the number that you need to enter instead of the question mark. Fortunately, as a hint, there are several answers.
   
   
   
   
2. You need to find a pattern in the second task. It seems a little easier here. Therefore, it is quite possible to do without prompts. Can you manage without spending a lot of time looking for a solution?

3. Finally, we offer another interesting task. And it is necessary to decide exactly the first example, because all subsequent ones only suggest what pattern is hidden here. Will it be possible to unmistakably deal with this task?

Tips to challenges

1. After analyzing the sequence, we came to the conclusion that each next number (beginning with the eight) is equal to the sum of the three numbers that are located in front of it. So 8 = 4 + 3 + 1, 15 = 8 + 4 + 3, and 27 = 15 + 8 + 4. Therefore, the number that hides behind the question mark is not so difficult to find: 8 + 15 + 27 = 50. And we really have that answer in the picture.

2. We immediately see that each subsequent number after the decimal point is multiplied by 3. And so in the last example, the same pattern should be preserved. Then the desired number is 81 * 3 = 243.
3. After analyzing the second, third and fourth lines, we guess that after the equal sign, the difference and sum of numbers from the left side are consistently recorded. And really: 7 – 4 = 3, and 7 + 4 = 11, so after the equal sign we see 311. Everything goes along with the other examples. Therefore, we find 6 – 2 = 4 and 6 + 2 = 8. Instead of a question mark, write down 48.

I think I got the right answers in every task. Or did you get other numbers? If so, write your options in the comments. Maybe we made a mistake somewhere.
