SUMMARY

The discussion revolves around the sequence 10, 9, 60, 90, 70, 66, and the challenge of identifying the next number. Participants suggest various interpretations, with one proposing the number 7 as a simple continuation. The conversation hints at the possibility of the sequence being an April Fools' joke, as it leads to a complex and seemingly arbitrary series of numbers. A reference to the Online Encyclopedia of Integer Sequences (OEIS) is provided, indicating that the series has been documented.

What reason do you have to think that there is a unique way to continue this?
 
May not be a unique way, but I think he just wants the simplest or any way. Either way it stumps me.
 
Well, if he want any way, 7 will do fine!:smile:

Hmm, I do notice that today is April 1.
 
Try the sequence 14,23,28,34,42,? At least it has an answer (particularly for NYC residents).
 
um...
..., 96, 10000000000, 10000000000000
 
This is an old problem. Here's the answer

10, 9, 60, 90, 70, 66, 314, Kermit, 7, 2, 2, 19, 43, Wyoming, 14343, 22, 43, 44, 1.654342, the Larch, 22, 23, 24, 0, 5, ...

The pattern should now be obvious.
 
Is this a big april fools joke to make us try our hardest to find a pattern and waste our time?
 
It's a real series: http://www.research.att.com/~njas/sequences/A052196
