Re^4: Reverse engineering a formula...

[vkon]

I think you understand my point (sorry for unperfect English) - sometimes tasks for finding a next number in some sequence of numbers are not useless, and such tasks help training ones brains.
OP has many flaws, and this is not really the sequence problem, and "Reverse engineering a formula" is a bad description of the problem

As a different note, our teacher said to us that the PI number contains, for example, encoded in it entire "War and Peace" by L.Tolstoy, starting from some position... you only need to find that N and enjoy the reading :)
While this is theoretically true, how can you benefit from this knowledge?

The pusillanimous goal of practising simple logical thinking (e.g. picking the easy option given a number sequence) pales to too little as compared with the value of using more comprehensive thinking to explore a subject, this being undermined by reaching an answer too superficially or habitually, because that in turn psychologically blocks further opportunity to see the bigger picture.

In this case, the OP needs at least to gather more information rather than find a logical substitute.

See Six Thinking Hats by Edward de Bono for a more precise and comprehensive evaluation of what missed opportunities are at stake.
