If the sum of first n terms of an AP is An + Bn² where A and B are constants, the common difference of AP will be

The first term of an AP of consecutive integers is p² + 1. The sum of 2p + 1 terms of this AP is

An AP consists of 31 terms. If its 16th term is m, then sum of all the terms of this AP is

If the nth term of an AP is (2n +1), then the sum of its first three terms is

If the common difference of an AP is 3, then a20 - a15 is

In an AP, if d = -2, n = 5 and an = 0, the value of a is

Two APs have the same common difference. . The first term of one of these is -1 and that of the other is -8. Then the difference between their 4th terms is

The list of numbers -10, -6, -2, 2, ___ is

In an AP, if a = 3.5, d = 0, n = 101, then a will be
