**Program to calculate Nth term and Sum of Arithmetic Progression in Java**

import java.util.Scanner; public class ArithmeticProgression { public static void main(String[] args) { Scanner input = new Scanner(System.in); double firstTerm = 0; double numberOfTerms = 0; double nthTerm = 0; double commonDifference = 0; double sum= 0; double term = 0; System.out.print("Enter the value of a (First Term) : "); firstTerm = input.nextDouble(); System.out.print("Enter the value of d (Common Difference) : "); commonDifference = input.nextDouble(); System.out.print("Enter the value of n (Number of terms) : "); numberOfTerms = input.nextDouble(); nthTerm = firstTerm + (numberOfTerms - 1) * commonDifference; sum = numberOfTerms * (2 * firstTerm + (numberOfTerms - 1) * commonDifference)/2; System.out.println(""); System.out.println("The Arithmetic Progression is as follows :"); for(int i = 0; i < numberOfTerms; i++){ term = firstTerm + i * commonDifference; System.out.print(term+" + "); } System.out.println("..."); System.out.println("The nthTerm of the series : " + nthTerm); System.out.println("The Sum of n terms of series : " + sum); } }
