Zane's bank charges him a fee for each day his account balance is less than $100. The arithmetic sequence {95.00, 89.50, 84.00, 78.50} describes Zane's bank balance for 4 days. Which explicit formula describes this arithmetic sequence?

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
