C++ program to find Nth term of the series 1, 5, 32, 288 ...
In this problem, we are given an integer N. Our task is to create a program to Find Nth term of series 1,5, 32, 288 ...Let’s take an example to understand the problem,InputN = 4Output288Explanation4th term − (4^4) + (3^3) + (2^2) + (1^1) = 256 + 27 + 4 + 1 = 288Solution ApproachA simple approach to solve the problem is by using the general formula for the nth term of the series. The formula for,Nth term = ( N^N ) + ( (N-1)^(N-1) ) + … + ( 2^2 ) + ( 1^1 )Program to illustrate the working of our solution,Example#include using namespace std; int calcNthTerm(int N) { if (N

In this problem, we are given an integer N. Our task is to create a program to Find Nth term of series 1,6, 18, 40, 75 ...Let’s take an example to understand the problem,InputN = 4Output40Explanation4th term − (4 * 4 * 5 ) / 2 = 40Solution ApproachA simple approach to solve the problem is by using the general formula for the nth term of the series. The formula for,Nth term = ( N * N * (N + 1) ) / 2Program to illustrate the working of our solution,Example#include using namespace std; int calcNthTerm(int N) { return ( (N*N*(N+1))/2 ); } int main() { int N = 5; cout

In this problem, we are given an integer N. Our task is to create a program to Find Nth term of series 5, 2, 19, 13, 41, 31, 71, 57…Let’s take an example to understand the problem, InputN = 5Output41ExplanationThe series is − 5, 2, 19, 13, 41, …Solution ApproachA simple approach to solve the problem is by using the general formula for the nth term of the series. The series has different formulas for even and odd values.The Nth term is given by, Nth term = (N-1)^2 + N, if N is even i.e N%2 == 0 Nth term ...
