Let x1,x2,....x100 be positive nos. such that the sum of two adjacent nos. is k(constant). (xi +x (i+1) = k for all i)

When I was teaching I would discuss the sequence described in the attachment in many different classes. The main purpose was to show there is nothing mysterious about compound interest, examples 2 and 3.
