Table schema:
CREATE TABLE table_name_77 (year INTEGER, rank VARCHAR, floors VARCHAR, height_ft__m_ VARCHAR)

Question: When a building is 292 (89) ft (m) tall, has less than 23 floors, and ranks less than 14, what is the average year?
SQL: SELECT AVG(year) FROM table_name_77 WHERE floors < 23 AND height_ft__m_ = "292 (89)" AND rank < 14
