What is the mathematical name for series such as 2, 6, 18, 54 etc where the next term in the sequence is obtained by multiplying the previous one by a fixed number?
Geometric progression Geometric progression In mathematics, a geometric progression, also known as a geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the "common ratio". For example, the sequence 2, 6, 18, 54, ... is a geometric progression with common ratio 3. Similarly 10, 5, 2.5, 1.25, ... is a geometric sequence with common ratio 1/2. Examples of a geometric sequence are powers "r" of a fixed number "r", such as 2 and 3. The general form of a geometric sequence is where "r" ≠
