FAQ’s Why is it Called a Geometric Sequence? Where, a is the first term and d is the common difference between two consecutive terms. In other words, a harmonic sequence is formed by taking the reciprocals of every term in an arithmetic sequence. The harmonic sequence is a sequence of numbers such that there is a common difference between the reciprocals of any two consecutive terms. All term of the sequence can be calculated by using the arithmetic sequence formula, which is, The arithmetic sequence is a sequence in which there is a common difference between every consecutive term. The formula of nth term of the geometric sequence is,.There are two types of geometric sequence formula for nth term. If there are n terms in a geometric sequence and r are the common ratio, then the geometric sequence is of the form, The geometric sequence formulas include two different formulas, one is to find the nth term of the sequence, and the second is to find the sum of n terms. The common ratio can be calculated by dividing two consecutive terms. It is obtained by multiplying three by each previous term.
The geometric sequence is also known as geometric progression.įor example, sequences 2, 6, 18, 54, … is a geometric sequence. The fixed non-zero number is called the common ratio of the sequence. What is a Geometric Sequence?Ī geometric sequence is a sequence of non-zero numbers where each term is calculated by multiplying the previous term by a fixed number.
