• Mon-x miles
  Tue-x+1 miles
  Wed-x+2 miles
  Thur-x+3 miles
  Fri-x+4 miles
  Sat-x+5 miles
  Sun- 3 miles
  so he travels 1 mile extra the previous day so on sunday he travelled 3 mile so on monday he travel 4 miles so accordingly tue-5,wed-6,thur-7,fri-8,sat-9
  totally for one week -(3+4+5+6+7+8+9)=42
  for 2 week =2*42=84 miles
