Step 2: Replace n by n+1 in an to get an+1 Step 3: Calculate an+1 - an Step 4: If an+1 - an is independent of n, the given sequence is an Arithmetic Progression. Otherwise, it is not an Arithmetic Progression. The following example will illustrate the procedure: Example: Show ...
Arithmetic is a branch of mathematics. Arithmetic includes different mathematical operations such as addition, subtraction, multiplication and division. Learn the basics of arithmetic with examples at BYJU’S.

Since the potential output is defined as \(Y_{p_{t}} = K_{t-1} / \nu \), we could equivalently define G in terms of the potential output (\(G_{t} = \left [{\Gamma }_{0} - {\Gamma }_{1} (u_{t-1} - u_{n})\right ] \nu Y_{p_{t}}\)). Arpaia and Turrini...
where ranges over all arithmetic progressions in . This can easily be seen to be a norm on functions that controls the norm. It is also basically controlled by the norm for -bounded functions ; indeed, if is an arithmetic progression in of some spacing , then we can write as the intersec...
In interval computations, the range of each intermediate result r is described by an interval r. To decrease excess interval width, we can keep some information on how r depends on the input x=(x 1,...,x n ). There are several successful methods of approximating this dependence; ...
Consider for instance the standard natural numbers as a model for arithmetic. Then the sequence of formulae “” for is finitely satisfiable in , but not satisfiable. However, if one takes a model of and passes to an ultrapower , whose elements consist of sequences in , modulo equivalence...
The MDI consists of two subindices—one on development equity and development achievements each—and is calculated in three versions for up to 171 countries for the years 1960–2018. By applying principal component analysis, we rely on the structure of the underlying data for the aggregation of ...
