Turtle is it 294?

I think it only fair I now require a justification for an answer before I assert its correctness, inasmuch as the range of answers is small. This isn't The Price is Right after all.

Truth is I did guess . I need to go right now but ill find out if its either 288, 294, 300, 306, or 312

I don’t understand how you decided on 125.Just b/c I feel like it Ill give one of the answer I came up with..which of course was wrong, but I just want to share one of the ideas I had

…

finally I found something ion common between the differences (need to multiply times negative three to get the next term) so multiplying by negative three and doing the math you get 125 which is of course, wrong

You got this difference table for the given sequence

1 2 4 8 15 30 50 100 1 2 4 7 15 20 50 1 2 3 8 5 30 1 1 5 -3 25 0 4 -8 28 4 -12 36 -16 48 64The difference table for the sequence extended by a 125 is

1 2 4 8 15 30 50 100 125 1 2 4 7 15 20 50 25 1 2 3 8 5 30 -25 1 1 5 -3 25 -55 0 4 -8 28 -80 4 -12 36 -108 -16 48 -144 64 -192 -256I don’t see a pattern, or understand what you mean by multiplying by -3 to get the next term.

Help, please!

PS: notice how wrapping tables done in a fixed-width font in code tags (# on the edit toolbar) can display them nicely.

couldnt figure out how to do them nicely:)

Ok so my last line was 4 (-12) and 36 so the next term is -108

28 + -108 is -80

25 plus -80 is -55

30 + -55 is -25

50 + -25 is 25

100 + 25 is 125

Here is the complete table

1 2 4 8 15 30 50 100 125

1 2 4 7 15 20 50 25

1 2 3 8 5 30 -25

1 1 5 (-3) 25 -55

0 4 (- 28 -80

4 (-12) 36 (-108)

sorry bill the answer isnt 147

Posted 18 September 2006 - 02:17 PM

Back to the drawing board...sorry bill the answer isnt 147

OK Hypographers, I have a pattern too...

2, 3, 4, 5, 5, 7, 6, 6, 7

I need to next 9 numbers to declare a winner.

Is it this sequence? When I factored all the numbers into a product of primes, I get some kind of funky pattern going on. I like the symmetry to it anyway. Thought I'd seen this before somewhere, just thought I ought to throw it out there.

1 11 11 1,2,3,5 2 12 11 4 12 12 8 22 12 15 11 35 30 12 35 50 12 55 100 22 55 49 11 77 7,11,13,17 98 12 77 154 12 7(11) 308 22 7(11) 221 11 13(17) 442 12 13(17) 578 12 17(17) 1156 22 17(17) 361 11 19(19) 19,23,29,31 722 12 19(19) 874 12 19(23) 1748 22 19(23) 899 11 29(31) 1798 12 29(31) 1922 12 31(31) 3844 22 31(31)

What if it's not a mathematical series? There are plenty of numeric series that aren't based on mathematics, perhaps we're making it too difficult for ourselves.

Posted 28 September 2006 - 07:04 PM

well maybe..Ive basically almost given up on this

Posted 28 September 2006 - 10:32 PM

1 tsp salt

2 tbs vanilla

4 eggs

8 cups of sugar

15 cups of flour

30 pecans chopped

50 raisins

100 chocolate chips

64 tbs butter

18 mins at

350 degrees F?

I'd really like to know what the next number is, this thing haunts me at night..

ok new tip:

the number has to be less than 100. LolI dont even know if this helps or not

Cmon people have we given up?? We now know it has to be less than 100, so our approach to it may change a bit.

Posted 01 October 2006 - 11:04 AM

I can't find a solution that fits all the criteria. I am interested to see what the answer is, because the criteria of being something a 5th grader could do with their basic understanding of math rules out complex or abstract solutions.Cmon people have we given up?? We now know it has to be less than 100, so our approach to it may change a bit.

It is time for your source to put up or admit it is an exercise of futility to get people to think about math.

Bill, knowing him i am 100% sure there is an answer. So yeah its obviously very complex in its simplicity I guess b/c you only need to use basic math to get to an answer and still it seems almost impossible to get one. However, even though something is difficult doesnt make it impossible.

Posted 02 October 2006 - 12:55 PM

I don't believe that there is a mathematical relationship that will lead you to an answer. Can we think of any other relationship between the numbers?

Posted 05 October 2006 - 04:03 PM

Mabey it just starts over as 1 or the mean wich is 24.375 but it still dosent make any sense:shrug:

Posted 05 October 2006 - 06:36 PM

oh guys I totally forgot to mentions this..Due to pgrmdave's post I talked to my calc teacher about the answer. He admitted that the answer is not PURELY mathematical, meaning the numbers can be applied to something else, he said something about it being applied to a social medium or something..

ok so lets start thinking about how to relate these numbers to something not related to math.

I know this is frustrating..
