Question: what is nth term in ap?
Answer: The progression -3, 0, 3, 6, 9 is an Arithmetic Progression (AP) with 3 as the common difference. The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tn = nth term and a = first term.
