합성수열의 N번째 항의 C 프로그램

처음 단어 "a", "d"의 공통 차이점 및 수열의 단어 수 "n"이 주어졌을 때. 시퀀스의 n번째 단어를 찾는 작업입니다.

따라서, 이 문제에 대한 프로그램을 작성하는 방법에 대해 논의하기 전에, 우리는 수학적 수열이 무엇인지 알아야 합니다.

arithmetic series or arithmetic sequence is a sequence of numbers in which the difference between two consecutive terms is constant.

like we have the first term,that is a = 5,difference1and the n-th term we are looking for should be3therefore,the series should be:5。6。7、7,so the output must be

。-

therefore,we can say that the n-th term of the arithmetic series will be similar to1 AP1
therefore,we can say that the n-th term of the arithmetic series will be similar to2 AP1 + = a2-1) * d
therefore,we can say that the n-th term of the arithmetic series will be similar to3 AP1 + = a3-1) * d
(1 + (n-1) *

..APn = a +(n-1)* therefore the formula will be AP = a

example

nth term will be2, d=1, n=5
Input: a= 6
d.
2, 3, 4, 5, 6 Explanation: The series will be: 6
nth term will be7, d=2, n=3
Input: a= 11

Output:-

  • we will use to solve the given problem

  • with the first term A,common difference D and N as the series number. +then by (A-1)* (N

  • D)calculate the n-th term

return the output obtained from the above calculation.

algorithm
   Step 1 -Start
      > In function int nth_ap(int a, int d, int n) + (n - 1) * d)
   Step 2 -> int main()      Declare and initialize the inputs a=2, d=1, n=5
      Print The result obtained from calling the function nth_ap(a,d,n)
Stop

example

#include <stdio.h>
int nth_ap(int a, int d, int n) {
   //use the formula to find
   //the n-th term t(n)= a(1)+(n-1)* d-
   return (a + (n - 1) * d);
}
//main function
int main() {
   //starting number
   int a = 2;
   //common point
   int d = 1;
   //the Nth noun
   int n = 5;
   printf("The %dth term of AP :%d\n", n, nth_ap(a,d,n));
   return 0;
}

output result

The 5the term of the series is: 6
