Chapter 8, Problem 32(choose chapter or problem)
The value of each term of a sequence a1, a2, . . . , a2k is a positive integer and 2k X i = 1 ai = 3k. Show that for each positive integer m k, there exist integers r and s with 1 r < s 2k such that s X i=r+1 ai = m. [Hint: Consider the cases when m < k and m = k separately.]
