Question: what was the average total property & casualty investment earnings net realized capital gains from 2002 to 2004
Evidence:
table_2: the net realized capital gains ( losses ) after-tax of 2004 is $ 87 ; the net realized capital gains ( losses ) after-tax of 2003 is $ 165 ; the net realized capital gains ( losses ) after-tax of 2002 is $ -44 ( 44 ) ;
Program: add(87, 165), add(#0, -44), add(#1, const_3), divide(#2, const_2)
