The Calculator helps calculating the Sum of Geometric Progression
In mathematics, an geometric progression or 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 instance, the sequence 2,6,18,54,162 is an sequence progression with common ratio of 3.
The sum of Geometric Progression is equal to:
Sn = a1 .( qn-1-1)/(q-1)
Where:
a1 is the first term of an geometric progression.
q is the common ratio.
n is the number of terms in the geometric progression.
Sn is the sum of n terms in the geometric progression.
