Answer:
Senators: four years ; Representatives: two years
Step-by-step explanation:
The Senate is the upper house of the Legislature. Its members are elected on a partisan basis for four-year terms, concurrent with the election of the Governor of Michigan.
The House of Representatives is the lower house of the Legislature. Its members are elected on a partisan basis for two-year terms, at the same time at which Representatives in U.S. Congress are chosen.
