 Hi and welcome to the session. I am Deepika here. Let us discuss the question whether the following form an AP If they form an AP, find the common difference D and write 3 more terms root 3, root 6, root 9, root 12 and so on. Let's start the solution. Our given list of numbers is 3, root 6, root 9, root 12 and so on. We have A2-A1 is equal to root 6-root 3. A3-A2 is equal to root 9-root 6. That is A2-A1 is not equal to A3-A2. Therefore this does not form an AP. Since A2-A1 is not equal to A3-A2, therefore the given list of numbers does not form an AP. Hence the answer for the above question is no. I hope the question is clear to you. Bye and have a good day.
