Question 1163812: Please dont give me an answer to the problem. I am not doing any homework. I am just learning (self educating). Just show me what is the approach. I know the formula for the sum of a sequence. But that on one side, and the given sum on the other side, I am stuck with solving the inequality and establishing a AP sequence.
Question: Find the arithmatic sequence which has the sum of its n terms equal to 2n^2+3n
Thank you

You can put this solution on YOUR website! I posted this question and since then, I figuered out where I went astray. I was thinking in terms of inequality, instead the sigma notation and plugging the value of n for 0, 1, 2 etc.
Thank you, (and I am glad I could prevent a teacher wasting his time answering this one)
