Fairly simple stuff:

7,19,29,37,47,59,67,79,89,97,... Highest prime less than 10x. I suppose this

sequence has repeated terms for the larger prime gaps.

23,67,89,199,331,353,397,419,463,617,661,683,...Primes that are 1mod11.

3,5,11,31,127,709,...The 3rd prime is 5, the 5th prime is 11, the 11th prime

is 31,...

2,3,5,7,11,13,17,23,31,41,43,53,...Primes that have digit sums less than 10.
