9 (a) In an arithmetic progression the sum of the first ten terms is 400 and the sum of the next ten terms is 1000. Find the common difference and the first term.[5](b) A geometric progression has first term a. common ratio r and sum to infinity 6. A second geometric progression...
In this paper we obtain optimal bounds for the length of the longest arithmetic progression in various kinds of sum-sets. As an application, we derive a sharp estimate for the number of sets A of residues modulo a prime n such that no subsum of A equals x modulo n, where x is a ...
An arithmetic progression is a sequence where the differences between every two consecutive terms are the same. In an arithmetic progression, each number is obtained by adding a fixed number to the previous term.
8 (a) An arithmetic progression has 14 terms. The sum of all the odd terms is 161 and the sum of all even terms is 182. Find the last term of the progression.[3 marks](b) Jay works as a supervisor in a factory. Every subsequent year, his monthly salary is increased by 10%. ...
Sum of the First n Terms of Arithmetic ProgressionThe formula for the first n terms of an arithmetic progression isFormula (First n Numbers in an AP): Sn = n/2 [ 2a + ( n – 1 ) d ] where Sn = sum of the n termsn = total termsa = first termd = common difference...
