WebA geometric progression, also known as a geometric sequence, is an ordered list of numbers in which each term after the first is found by multiplying the previous one by a fixed non-zero number called the common ratio r r . For example, the sequence 2, 6, 18, 54, \cdots 2,6,18,54,⋯ is a geometric progression with common ratio 3 3 . Similarly WebA geometric sequence is a sequence of terms (or numbers) where all ratios of every two consecutive terms give the same value (which is called the common ratio). Considering a geometric sequence whose first term is 'a' and whose common ratio is 'r', the geometric sequence formulas are: The n th term of geometric sequence = a r n-1.
