Geometric progression is an ordered sequence of real numbers or terms, obtained by multiplying the
previous one number by a fixed quantity (q) called common ratio.
a) 2,4,8,16. This sequence of numbers is a geometric progression because dividing the term 4 by 2 or, 8/4, 16/8, the result is always a constant equal to 2.
The sequence 2,5,6,10 is not a geometric progression, because by dividing any two subsequent terms in the series, the results are not the same.
When the series starts by a smaller to the greater term , the progression shows exponential growth and the constant value is always greater than 1. Otherwise the progression shows a exponential decay .and the constant value is less than 1.
Use the point as decimal separator. Ex. For the number 8,182.46 enter 8182.46; The results are automatically displayed after you click on "Calculate."
Note: The accuracy of the calculator and its applicability to particular cases is not guaranteed. The assistance, customized by qualified professional is recommended.
