When Xiao Ming calculates 5. A + B.9, he miscalculates 8. A + B.6, and the result is 10. Then 5. A + B.9 =? If you add 7 to a and divide B by sum, the quotient is 13, the remainder is 0, and a =? In a division problem, divisor and quotient are both 19. What is the maximum remainder? What is the divisor?

Because a + 6 = 1, so a = 4
So 8 + B = 9, B = 1
Then 5. A + B.9 = 7.3
a=12b+8,
A + 7 = 13b, so a = 188, B = 15
The maximum remainder is 19,
Divisor = 19 * 19 + 18 = 379

Subtract 1 / 2 of 2008 and the remaining 1 / 4 Until the last minus the remaining 1 / 2008, the final result is ()

Do you subtract one third from the middle? If so
2008*(1-1/2)*(1-1/3)*...*(1-1/2008)
=2008 * 1 / 2 * 2 / 3 *... * 2007 / 2008
(middle numerator, denominator is missing)
=2008*1/2008
=1

2 / 1, 5 / 3, 13 / 8, 34 / 21, 89 / 55, (), () fill in the blanks according to the rules

2 / 1, 5 / 3, 13 / 8, 34 / 21, 89 / 55, (233 / 144), (610 / 377) fill in the blanks according to the rules

What are the last two numbers of 22, 2, 44, 3 and 55?

If you look at this horizontal number, the first number is 1, the third number is 2, the second number is 22, the fourth number is 44, and the sixth number is 55, you can get the rule that the nth number (n is odd) is one of the continuous natural numbers with the middle difference of 1 from 1, and the nth number (n is even) is 22. Add 22, 33, 44 in turn, then you can get the next number is 4, and then the next number is 66
If there is a lack, please give us more advice! I wish you a happy study

5 6 19 17 () - 55, what is in the brackets?
A：11 B：15 C:343 D：344

344 6 + 19 = 5 * 5; 19 + 17 = 6 * 6; 17 + 344 = 19 * 19; 344 + (- 55) = 17 * 17, the last two numbers add up to the square of the previous one

Find the law: n = 12345 M = 17193761 (corresponding) find the relationship between M and N?

M=1+6(N-1)

How to find the law of numbers? What's the fourth number on the seventh line?

If your line is the first line 121, the second line 12321, the third line 1367631, the fourth line 1 4 10 16 19 16 10 4 1, it should be 77. My idea is to vertically arrange each line from the third number (i.e. 3 6 10) to the penultimate number after each line. In fact, every a is straight from it

There is a group of numbers: 1, 6, 7, 12, 13, 18, 19, 24 If you write down according to this rule, the number in position 2006 is divided by 7, and the remainder is______ ．

Item 2006 is an even number item, it is: 2006 × 3 = 6018; 6018 △ 7 = 859 5. A: the remainder is 5. So the answer is 5

There is a series of natural numbers: 1,6,7,12,13,18,19 If you write it down according to the arrangement rule, what is the remainder after the number at position 113 is divided by 7?

From the meaning of the title
A.P. with odd first term of 1 and tolerance of 6
So item 113 is item 57 of the odd column
a57=1+（57-1）*6=337=48*7+1
So the remainder is one

The following is a set of natural numbers: 1 67 12 13 18 19... If you write according to this rule, how much is the number on the 133rd position divided by 7?

Mark all the numbers, and then the difference between the odd numbered numbers is 6
So the 133rd number is 397, so it's divided by 7 to make 5
