That is going to be true regardless of whatever fifth term he puts there.

What is the next term in the sequence

1, 2, 4, 8, 16...?

Well, it is, but it is the most likely that the 6th term they want is 3/16.

Why do you like 3 / 16?

I do not. It just looks like something that the question setter might like.

In what manner do you arrive at it?

By the way do you know about the demonstrations?

I noticed that the numerator of the terms with odd indexes are the same as their indexes, and the ones with even indexes were 1, so, I tried multiplying both the denominator and the numerator of those by the required power of 2. After that it was easy.

What demonstrations?

Wolfram of course! They have thousands of them.

Why not just download the notebook?

Hi;

There is code in there.

That is an animation. I cannot see any actual M code.

On the sides are cell grouping lines click them and you see some code.

But that is an authored version. The code is incomplete, I have another source notebook.

Try here for the source code.

http://demonstrations.wolfram.com/versi … rsion=0026

If you can not get that then here is what you want:

```
Manipulate[
Module[{m1 = {Reverse[pt1], {-1, 1} pt1},
m2 = {Reverse[pt2], {-1, 1} pt2}},
Graphics[MapIndexed[{Thickness[0.01 th^#2[[1]]], Line[#]} &,
NestList[
Flatten[Map[{{#[[2]], #[[2]] + m1.(#[[2]] - #[[1]])}, {#[[
2]], #[[2]] + m2.(#[[2]] - #[[1]])}} &, #],
1] &, {{{0, -1}, {0, 0}}}, gen]],
PlotRange -> {{-3, 3}, {-1, 5}}, ImageSize -> {500, 400}]], {{gen,
7, "generations"}, 3, 10, 1}, {{th, 0.7, "thickness ratio"}, 0.01,
1.2}, {{pt1, {-0.25, 0.75}}, {-3, -1}, {3, 3},
Locator}, {{pt2, {0.25, 0.75}}, {-3, -1}, {3, 3}, Locator}]
```

I have the result, but I do not yet know how to get it.

Actually, you were right. When I clicked on an unexpanded cell, the code was shown.

I have provided the code for you in the previous post. Cell grouping is a way to hide many cells. They appear as one. Also, it is a way to arrange work together.

Nothing beats M.

Thanks, anyway.

I am going to look at some more of them.

That is why I sent you the link. There are thousands with dozens coming in everyday. Did you drag on the branches as well as move the slider? What other language other than a CAS could program that in 5 lines of code?

Yes, I have moved them. I will try and change their code to get the tree from one of the eulerproject problems.

Oh, have you seen my solution of phro's "bobbym's YOB" puzzle?

I worked on that one for Agnishom and solved it.

No, I have not seen your solution. I have been busy working on a full solution to the sudoku thread.

I do not remember your solution.

It might not be the same problem but I worked on a projecteuler problem. I think it was #300? It should have me on the solution list.

Yes, the one you and phrontister are working on. There are two questions that need answering.

It is sort of a combination of sudoku and a rubiks cube.
