Question 4 Find the number of terms in the following arithmetic progressions -104, -91, -78, ..., 234

For each successive presidential term from Franklin Pierce (the 14th president, elected in 1853) to George W. H. Bush (41st president), the party affiliation controlling the White House is shown below, where R designates Republican and D designates Democrat. (Reference: The New York Times Almanac.)Historical Note: We start this sequence with the 14th president because earlier presidents belonged to political parties such as the Federalist or Wigg party (not Democratic or Republican). In cases in which a president died in office or resigned, the period during which the vice president finished the term is not counted as a new term. The one exception is the case in which Lincoln (a Republican) was assassinated and the vice president Johnson (a Democrat) finished the term.
