Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_name_1 ( gross_debt_in_ INTEGER, debt_held_by_public__$billions_ VARCHAR, end_of_fiscal_year VARCHAR, as__percentage_of_gdp_low_high VARCHAR )

### Question ###
For End of Fiscal Years past 1980 that also have as % of GDP Low-High of 83.4-84.4, and a Debt Held By Public ($Billions) smaller than 7,552 what would be the average Gross Debt in $Billions undeflated Treas. in said years?

### Accurate SQL ###

SELECT AVG(gross_debt_in_) AS $billions_undeflated_treas FROM table_name_1 WHERE end_of_fiscal_year > 1980 AND as__percentage_of_gdp_low_high = "83.4-84.4" AND debt_held_by_public__$billions_ < 7 OFFSET 552
