Visualising an AP We can visualise any AP in a graph, and it looks like a straight line For AP 1, 4, 9, 13, …. We can plot this in a graph Let x represent term number (like 1st, 2nd, 3rd term) And, y represent value of the term We get a table like this Wit points (1, 1), (2, 5), (3, 9), (4, 13), (5, 17) And, plotting this in a graph, we get Let’s do another example Bank FD Example Let’s put put money into a standard Indian Bank FD that pays Simple Interest We deposit ₹ 1,000 with 15% interest every year Our graph would look like
