So here is a test of perspicacity. What is the next number in the following sequence:

1,3,22,66,70,81,?

Since to answer this question one must first guess how the numbers in the sequence are related, and then with that execute the non-trivial task of providing the next number, one point will be provided to the first person to provide the next correct number in the sequence and one point to the first person who can identify how the sequence is formed.

This could result in a tie, so as a tie breaker what can one observe in the following number?

10,213,223
