(b) If a majority of the votes cast on a question placed on the ballot pursuant to paragraph (a) of this subsection (3) are in favor of increasing the membership, the board of county commissioners shall pass a resolution increasing the membership to five members and providing for the election of the increased number of county commissioners at the next general election according to the procedure for election specified in such question which received the largest number of votes cast.
