Question: `qQuery 1.1.20 1 / 3, 3 / 5, 5/7, 7/9, ... Probable next element.

Your solution:

1 / 3, 3 / 5, 5/7, 7/9,

9/11 is the probable next element derived from the pattern above

Question: `qQuery 1.1.23 This problem wasn't assigned, but you should be able to make a good attempt: 1, 8, 27, 64, ... What is the probable next element?

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution:

1, 8, 27, 64 - did not get this one

1*1

confidence rating #$&*: none

&#Your response did not agree with the given solution in all details, and you should therefore have addressed the discrepancy with a full self-critique, detailing the discrepancy and demonstrating exactly what you do and do not understand about the parts of the given solution on which your solution didn't agree, and if necessary asking specific questions (to which I will respond).

Question: `qQuery 1.1.36 11 * 11 = 121, 111 * 111 = 12321 1111 * 1111 = 1234321; next equation, verify.

Your solution: 123454321

confidence rating #$&*: very confident. looked at the pattern and then used a calculator

Question: `qDo you think this sequence would continue in this manner forever? Why or why not?

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution: pattern continues until the 10th iteration. at that point the product becomes 1234567900987654321 and the pattern is destroyed

Question: `qQuery 1.1.46 1 + 2 + 3 + ... + 2000 by Gauss' method

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution:

1+2000 = 200`

2+`1999 = 2001

3+1998 = 2001

this continues 1000 times--> 2001 * 1000 = 2001000

Question: `qQuery 1.1.57 142857 * 1, 2, 3, 4, 5, 6. What happens with 7? Give your solution to the problem as stated in the text.

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution:

142857*1 = 142857

142857*2 = 285714

142857*3 = 428571

142857*4 = 571428

142857*5 = 714285

142857*6 = 857142

142857*7 = 999999

From 1 to 6, the products consists of all the same numbers used in different order. When you get to 7 the product breaks the patterm

Question: `qWhat does this problem show you about the nature of inductive reasoning?

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution: inductive reasoning would indicate that the same pattern would continue based on previous examples. However, if you cannot see the results of all patterns, you cannot verify that the results of inductive reasoning is correct. Therefore, it is not really an accurate method.
