71,53,11,81,33,77,39,47,54,77,76,

There are trillions of patterns that would do.  One pattern is to 
start the whole thing over after each 11 terms, like this:

71,53,11,81,33,77,39,47,54,77,76,71,53,11,81,33,77,39,47,54,77,76,
71,53,11,81,33,77,39,47,54,77,76,71,53,11,81,33,77,39,47,54,77,76,
71,53,11,81,33,77,39,47,54,77,76,71,53,11,81,33,77,39,47,54,77,76,
71,53,11,81,33,77,39,47,54,77,76,71,53,11,81,33,77,39,47,54,77,76,
...

That pattern fits the condition that all numbers in the sequence 
are less than 100.

The next three numbers are the same as the first three: 71,53,11.
