    【Question】
    What is the weekly average number of fraud incidents that were reported in January 2018? Provide the description of the location where the majority of fraud incidents occurred in the said month. fraud incident refers to title = 'Fraud'; reported in January 2018 refers to Substr(date, 1, 1) = '1' AND Substr(date, 5, 4) = '2018'; description of location refers to location_description; weekly average refers to Divide (Count(report_no), 4); majority of incidents occurred refers to Max(Count(location_description))

    【Evidence】
    fraud incident refers to title = 'Fraud'; reported in January 2018 refers to Substr(date, 1, 1) = '1' AND Substr(date, 5, 4) = '2018'; description of location refers to location_description; weekly average refers to Divide (Count(report_no), 4); majority of incidents occurred refers to Max(Count(location_description))

    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT CAST(COUNT(T1.fbi_code_no) AS REAL) / 4 FROM FBI_Code AS T1 INNER JOIN Crime AS T2 ON T1.fbi_code_no = T2.fbi_code_no WHERE SUBSTR(T2.date, 1, 1) = '1' AND SUBSTR(T2.date, 5, 4) = '2018'
