8 eager students are in line to take their seats in the first row, which has exactly 8 chairs. The student decides that the first person could pick any chair to sit on. For the rest, they have to pick a seat that is immediately next to another seated student. How many ways are there for the students to seat themselves according to this method?

• If the student sits on 1st chair, then rest of the students have 7 seats to sit on ->1 way
  if the student sits on 2nd chair, then rest have 1 option, similarly....there are 8 possible ways...
