Geometric Progression Calculator

How to calculate geometric progression?

To solve and output a geometric progression, you must specify the following initial data: the value of the progression member (and its ordinal number), the denominator of the progression, and its length. After writing all the data and clicking on the "Calculate" button, the problem will be solved - you will see a sequence of numbers of the geometric progression.

Formula for finding the n-th term of a geometric progression:

b_n = b₁ × q^{(n – 1)}, b₁ – the first term of the progression, n is the number of terms of the progression, q is the denominator of the progression.

With our calculator you can easily and quickly find any member of the progression. To do this, you do not need to know the value of the first term, you can specify the value of any known term, and the calculator will do all the necessary calculations to find the n-th term of the geometric progression.

Limitations in calculations on our calculator: the length of the geometric progression must not exceed 100, the index of the first member cannot be less than 1, the values ​​of the parameters must be numeric and greater than 0. Based on the characteristics and definition of a geometric progression, the denominator and the first term of the progression cannot be equal to zero.
