Can anyone help me calculate an approximate number for a math problem?

Levels 1-3 per dot suit: 237 3=79;

Levels 1-5 per dot flower: 588 10=;

Levels 1-7 per dot flower: 1020 18=;

Levels 1-9 per dot flower: 1517 29=;

Levels 1-11 per dot suit: 2071 42=;

Levels 1-13 per dot flower: 2675 57=;

Level 3-5 cost difference:;

Level 5-7 cost difference:;

Level 7-9 cost difference:;

Level 9-11 cost difference:;

Level 11-13 cost difference:;

As can be seen from the cost difference, except for the large cost difference between level 3 and level 5, the rest of the cost difference is not much different. Ignoring the cost difference between level 3 and level 5, and averaging the remaining four cost differences, the average cost difference is: (.

The average cost difference can be thought of as a decrease in the cost for each two levels of increase. That is, starting from level 13, the cost decreases for every 2 levels raised, so:

That is, increasing the level by another 10 levels (levels 1-23) can make each point of attribute need to cost about 32 yuan level.

Hehe, I roughly calculated, if you look at the data rules you gave, it will be 32 yuan when it is level 23.

It depends on the game setting, which is about level 30.

Starting with the second number, each number is 1 more than the previous number

66 should be followed by 264

Let the original n consecutive positive integers, then.

n(n+1)/22005

The solution is n uninteresting).

So, n minimum is 63

At this time n(n+1) 2 63(63 1) 2 2016

So, the missing number is.

1.The elder sister originally had 315*4 7 = 180 yuan, and the younger sister had 315-180 = 135 yuan.

135 (1-5 14) = 210 RMB.

2.108*(1-2 9) (1-3 10)-108=120-108=12 people.

3.2*60% kg.

315x4 7 = the amount of money before the sister did not withdraw the money.

315x3 7 = the amount of money in the younger brother.

The younger brother's money accounts for 9 14 of the money of the two people after the withdrawal, so the total amount of money is 315x3 7 divided by 9 14

Question 2 The same is true.

The number of boys has always remained the same. It's just that at first it's seven out of nine, and then it's seven out of ten, and then it's seven tenths of a tenth, and it's just seven times nineths divided by seven tenths. Then 12 more girls came.

The same is true for the third question.

The total amount of potions remains the same. It's just that it was 60% at the beginning, and then it was accounted for.

1.Suppose you take x yuan 315 * 4 7 = 180 180-x = 5 14 (315-x) x = 105 so take 105 yuan and leave 210.

2.Suppose x people come 108*2 9=24 24+x =(108+x)*3 10 (Can you skip the calculation step?。。。 Then x=12.

3.Suppose you add water x kg 2 * 6 10 = kg of medicine kg of water x = 238 floor lord for the sake of my lack of merit and hard work... Woo woo woo ...

This is an intellectual problem that is unsolvable in decimal and solvable in other decimal systems.

If it's in eleven.

15 is equivalent to 16 in decimal, 30 is equivalent to 33 in decimal, then under eleven.

Equivalent to 1 + 16 + 16 = 33

If it's in thirteen decimal system.

13 is equivalent to 16 in decimal

30 is equivalent to 39 in decimal, then under decimal system.

Equivalent to 7 + 16 + 16 = 39

The intercept from the x-axis is the absolute value of y 0, so it is 3

Similarly, when the intercept of the y-axis is x 0, the absolute value of the y-value is 4
