Answer:
C. w–2(n–1)
Step-by-step explanation:
One way to think of this is that the smallest is the n-th term of an arithmetic sequence with w as the first term and -2 as the common difference. The formula for the n-th term is ...
an = a1 + d(n -1)
Filling in the given values, we have ...
smallest number = w -2(n -1) . . . . . matches choice C
It is b because b is the most logical answer
C=2(pi)r, so divide 215 by 6.28. r(radius)=34.2
D. The solution is 35, which represents the number of miles she runs each week.
