Solve the problem.
-A physical activity class requires students to jog around an indoor track. For the first week of class the students jog 300 m around the track each day. Each week thereafter, the students increase the Distance jogged by 125 m. Write the nth term of a sequence defining the number of meters joggedBEach day by the students in the nth week of class.
A) $a _ { n } = 125 n + 175$
B) $a _ { n } = 125 n + 300$
C) $a _ { n } = 175 n + 125$
D) $a _ { n } = 300 n + 125$

Quizplus · Accepted Answer

The sequence starts at 300 meters and increases by 125 meters each week. The formula for the nth term is $a_n = 125(n - 1) + 300$, which simplifies to $a_n = 125n + 175$.
