Primary school digital law
1,5,10,（）,11,（）
Please explain the algorithm

1,5,10,50,11,55
Rule: odd number: 1 + 10 = 11, the second (10) is 10 times of the first (1)
So, even number: 5 + 50 = 55, the second (50) is 10 times of the first (5)

Find the rule number problem

————What should I fill in the next line? Why
Please explain the law

You don't have to look at line 2
Because the 1 2 in line 2 means that there is a 2 in the line above
Similarly, the third line refers to a 1 and a 2 in line 2
Line 4 means that there are three 1's and one 2's in line 3
Line 5 means that there is a 3 and a 12 in line 4
Line 6 means that there is one 1, one 3 and one 12 in line 5
That is 1113112
I think the question is much more difficult than this one. The question is whether "4" appears. The question is the same

Find the law of numbers, 0,2,2,5,4, (), (), 11,8, what to fill in brackets and why

8 and 6, 2 for odd column and 3 for even column

What are the numbers in brackets 1,1,2,7, ()?

The second 1 = the first 1 × 2-1
2 = second 1 × 3-1
7=2×4-1
Then 7 × 5-1 = 34 in brackets

There are & nbsp; 2 & nbsp; cent and & nbsp; 5 & nbsp; cent coins in Xiaogang's Bank. Xiaogang counts them, and there are & nbsp; 194 & nbsp; cent in total. How many coins are there in each coin?

Suppose all the coins are 2 cents: 2 × 70 = 140 (cents), 194-140 = 54 (cents), then the coins of 5 cents are 54 △ 5-2, = 54 △ 3, = 18 (coins), then the coins of 2 cents are 70-18 = 52 (coins), answer: there are 52 coins of 2 cents and 18 coins of 5 cents

On a circular runway, a starts from point a and B starts from point B at the same time and goes in reverse. After 8 minutes, the two meet. After 6 minutes, a arrives at point B, and after 10 minutes, the two meet again. It takes a week for a circle______ Minutes

The speed ratio of Party A and Party B is: 8:6 = 4:3, 1 △ 1 (6 + 10) × 44 + 3, = 1 △ 116 × 47, = 1 △ 128, = 28 (minutes); a: it takes 28 points for a round trip
