Our task is to find the term for the given series at that particular position.Example Live Demo#include #include using namespace std; //calculating nth term of series int nthTerm(int n) {    return 2 * pow(n, 2) + n - 3; } int main() {    int N = 4;    cout

In this problem, we are given a number N. Our task is to create a Program to find N-th term of series 0, 2, 1, 3, 1, 5, 2, 7, 3...in C++.Problem Description − We are given the Series −0, 2, 1, 3, 1, 5, 2, 7, 3...N TermTo find the Nth term of this series, we will formula the general term of the series and then find the Nth term.Let’s take an example to understand the problem, Input − N = 7Output − 2Solution Approach :To solve the problem and find the general formula for the series. We need ... Read More

In this problem, we are given a number N. Our task is to create a program to find N-th term of series 0, 0, 2, 1, 4, 2, 6, 3, 8…in C++.Problem descriptionTo find the Nth term of the given series−0, 0, 2, 1, 4, 2, 6, 3, 8 .... N TermsWe will find the general term of the series.Let’s take an example to understand the problem, InputN = 8Output3Solution ApproachTo find the general term of the series, we need to closely observe the series. This series is a bit difficult to recognize as it is a mixture of two ... Read More

In this problem, we are given three numbers A, B, and N. Our task is to create a program to find Nth term divisible by A or B in C++.Problem DescriptionThe Nth Term divisible by A or B. Here, we will find the term n number term which is divisible by number A or B. For this, we will count till nth numbers that are divisible by A or B.Let’s take an example to understand the problem, InputA = 4, B = 3, N = 5Output9ExplanationThe terms the are divisible by 3 and 4 are −3, 4, 6, 8, 9, ...
