Okay, Gerald Ford served 1 term from 1974 to 1977. John F. Kennedy served a partial term (because of his assassination) from 1961 to 1963. Richard Nixon served 1 full term as well as a partial second (because he resigned from office) from 1969 to 1974. Lyndon B Johnson served a partial term (because he was sworn in after Kennedy's assassination) and then a full term after that from 1963 to 1969.
So, you answer would be John F. Kennedy, Lyndon B. Johnson, Richard Nixon, then Gerald Ford.
Hope this helps!
