Question

Which of the following best defines an Arithmetic Progression (A.P.)?

Options

• A list of numbers in which terms are arranged in decreasing order only

• A list of numbers in which each term is obtained by multiplying the same fixed number

• A sequence in which the sum of consecutive terms is constant

• A sequence in which the difference between consecutive terms is constant

Answer 1

An Arithmetic Progression (A.P.) is a sequence in which the difference between consecutive terms is constant. The fixed number added to obtain each term from the previous term is called the common difference \(d\).
