Question

What is the general form of an A.P. with first term \(a\) and common difference \(d\)?

Options

• \(a,\; a + d,\; a + 2d,\; a + 3d, \ldots\)

• \(a,\; 2a,\; 3a,\; 4a, \ldots\)

• \(a,\; a - d,\; a - 2d,\; a - 3d, \ldots\)

• \(a,\; ad,\; ad^{2},\; ad^{3}, \ldots\)

Answer 1

In the general form \(a,\; a + d,\; a + 2d,\; a + 3d, \ldots\), \(a\) is the first term and \(d\) is the common difference. Each term is obtained by adding \(d\) to the previous term.
