Table schema:
CREATE TABLE table_name_2 (rank__timeslot_ INTEGER, rank__night_ VARCHAR, rating VARCHAR)

Question: What is the timeslor rank for the episode with larger than 2.9 rating, rating/share of 2.6/8 and rank for the night higher than 5?
SQL: SELECT AVG(rank__timeslot_) FROM table_name_2 WHERE rating > 2.9 AND rating / SHARE(18 - 49) = 2.6 / 8 AND rank__night_ > 5
