Here's the Solution to this Question
1.Denote by cn the cost of travelling for n miles. Then
cn=cn-1+1 if n>4 and cn=cn-1=7.5 else.
Explicit formula:
cn=n+3.5 if n>4 and cn=7.5 else.
2. tn = n2 -1, n less than or equal to 1.
t1 = 12-1 = 0
t2 = 22-1=3
t3 = 32-1=8
t4 = 42-1=15
t5 = 52-1=24
t55 = 552-1=3024
