given any two numbers a,b and an upper and lower bound for the sum of reciprocals of a certain class of integers between a and b, without any direct calculation how can optimal upper and lower bounds for the number of terms in the sum be found

given any two numbers k,j what is the largest sequence of integers such that the sum of any k consecutive terms is negative and the sum of any j consecutive terms is positive and how may we find a subset containing k of the first n numbers such that out of all subsets with k elements, this...
