RD Sharma Solutions for Class 11 Maths Chapter 20 Geometric Progressions

A sequence of non-zero numbers is called a geometric progression if the ratio of a term and the term preceding it, is always a constant quantity. In mathematics, a sequence of numbers in which each number is obtained from the previous one by multiplying by a constant. For example, the sequence 1, 2, 4, 8, 16, 32 ... (in which each number is multiplied by 2 to get the next one) is a geometric progression.
