Administrators, playing their administrator games… :rolleyes:

😉

(By the way, the sequence 1, 3, 5, 7, can’t be odd primes, since 1 isn’t prime.)

Sorry, I totally goofed up the sequence, so edited it out. Didn’t realize anyone had seen it.

OK, so the sequence 1, 3, 5, 7, 11 is the set of odd primes plus the multiplicative identity. Big deal.
