Find the nth term of a sequence 1, 1, 2, 3, 5, 8, 13, 21, 34, . .

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

// function to find the nth term of sequence

int nth_fib(int n)

{

   // base case

   if (n <= 1)

       return n;

   return nth_fib(n-1) + nth_fib(n-2);

}

// main function

int main()

{

   // variables

int n,term;

cout<<"enter the term:";

// read the value of n

cin>>n;

// call the function

term=nth_fib(n);

// prinnt the nth term

cout<<n<<"th term in the sequence is: "<<term<<endl;

return 0;

}

Explanation:

The given sequence is Fibonacci sequence.Here first and second term is 1 and then 3rd term is sum of previous two terms. Similarly 4th term is sum of 2nd and 3rd term. Using this property of the sequence, we can find the nth term of the sequence. First read the term from user and call the function nth_fib() with parameter n. this function will return nth term of the sequence.If term is 1 or 2 then it will return 1.

Output:

enter the term:6

6th term in the sequence is: 8

answer; i believe that technician a is correct;

i don't think so. although it would be nice. i am pretty sure that was an option an update or two ago. i guess they want you to stay 14 forever. haha.
