 Hello and welcome to the session. I am Deepika here. Let's discuss the question. Write first four terms of the AP when the first term A and the common difference D are given as follows. A is equal to minus 2 and D is equal to 0. Now we know that an automatic progression is a list of numbers in which each term is obtained by adding a fixed number to the preceding term except the first term and that fixed number is called the common difference of the AP. It can be positive, negative or zero. So if first term take progression, so this is the key idea behind that question we will take the help of this key idea to solve the above question. So let's start the solution. Now it is given that A is equal to minus 2 and common difference D is equal to 0. Now according to our key idea, A progression therefore A which is equal to minus 2 A plus D is an automatic progression therefore minus 2, minus 2, minus 2 and again minus 2 are the first four terms of the AP. The answer for the above question is that minus 2 and minus 2 are the first four terms of the AP if A is equal to minus 2 and D is equal to 0. So this is our answer. I hope the solution is clear to you. Bye and take care.
