Answer:
T = a + (n-1)d
Step-by-step explanation:
The arithmetic progression formula could be used to represent the series
T = a + (n-1)d
Where a = number of miles before increase
d = intended additional number of miles each day
n= number of days
Hence on the 2nd day, number of miles to be covered by Jeff will be
T = a + (2-1)d = a + d
