## What is Fibonacci number in C#?

In case of fibonacci series, next number is the sum of previous two numbers for example 0, 1, 1, 2, 3, 5, 8, 13, 21 etc. The first two numbers of fibonacci series are 0 and 1.

## What does each Fibonacci number mean?

In the Fibonacci sequence of numbers, each number is approximately 1.618 times greater than the preceding number. For example, 21/13 = 1.615 while 55/34 = 1.618. In the key Fibonacci ratios, ratio 61.8% is obtained by dividing one number in the series by the number that follows it.

### What is fibonacci series example?

Fibonacci Sequence = 0, 1, 1, 2, 3, 5, 8, 13, 21, …. “3” is obtained by adding the third and fourth term (1+2) and so on. For example, the next term after 21 can be found by adding 13 and 21. Therefore, the next term in the sequence is 34.

### What is prime number logic?

Logic − We will divide 42 by every number greater than 1 and smaller than 42. So, 42/2 = 21 i.e. 42 is divisible by 2, this means 42 is not a prime number because it is divisible by another number. 7 is not divisible by 6, This means that 7 is divisible by only 1 and 7 this means 7 is a prime number.

**What is N factorial?**

The factorial (denoted or represented as n!) for a positive number or integer (which is denoted by n) is the product of all the positive numbers preceding or equivalent to n (the positive integer).

**What are the Fibonacci numbers?**

What are Fibonacci Numbers? Fibonacci Numbers are the numbers found in an integer sequence referred to as the Fibonacci sequence. The sequence is a series of numbers characterized by the fact that every number is the sum of the two numbers preceding it.
