If A denotes the property that two elements of A = {1, 5, 9, 13 …, 1093} add up to 1094, then the maximum number of elements in A can be

Since the elements in A are in A.P., therefore, the number of elements in A=1093−14+1=274.Since, sum of equidistant terms in A.P. is equal to the sum of first and last term = 1 + 1093 = 1094.⇒ maximum number of elements in A, that add up to 1094 =2742=137.
