Question

Which of the following is the general form of an Arithmetic Progression?

पर्याय

• \[a,\; a + d,\; a + 2d, \ldots\]

• \[a,\; 2a,\; 3a, \ldots\]

• \[a,\; ar,\; ar^2, \ldots\]

• \[a,\; a + d,\; a + d^2, \ldots\]

Answer 1

An A.P. has the form \[a,\; a + d,\; a + 2d, \ldots,\] where each term is obtained by adding the common difference d. The form \[a,\; ar,\; ar^2, \ldots\] is not an Arithmetic Progression.
