1.	If a1, a2……… are in AP thena1^-1, a2^-1……… are in __________(a) An airthmetic sequence(b) A geometic progression(c) Airthmetico-geometric progression(d) None of the mentionedI got this question in quiz.I need to ask this question from Harmonic Sequences in chapter Basic Structures: Sets, Functions, Sequences, Sums and Matrices of Discrete Mathematics
Answer» Right CHOICE is (d) NONE of the mentioned To elaborate: If a1, a2……… are in AP, then a1^-1, a2^-1………are in HARMONIC PROGRESSION.
