Arithmetic Progression is an ordered sequence of real numbers or terms where the difference between a term and its antecedent called common difference is same . Example: 2, 4, 6,8,10. This sequence of numbers is an Arithmetic Progression because difference 4 minus the term 2 or, 8-6, 10-8, is always a constant, equal to 2. The sequence 2, 5,6,10 is not an Arithmetic Progression, because difference from any term by its antecedent is not equal. When the series starts by a smaller to the greater term, the progression shows a growing sequence, and the common difference is always a positive number. Otherwise the progression shows a descending sequence, and the common difference is a negative number. 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.
