technology and computing programming languages# What is nth Fibonacci number?

Last Updated: 20th January, 2020

**nth Fibonacci number**interms of the two before it: the n-th

**Fibonacci number**is thesum of the (n-1)th and the (n-2)th. So to calculate the 100th

**Fibonacci number**, for instance, we need to compute all the99 values before it first - quite a task, even with acalculator!

Accordingly, what is the nth term of Fibonacci sequence?

A **sequence** of numbers such as 2, 4, 8, 16, it iscalled a geometric series . First, calculate the first 20 numbersin the **Fibonacci sequence**. Remember that the formula to findthe **nth term** of the **sequence** (denoted by F[n]) isF[n-1] + F[n-2].

Furthermore, what is the 10th Fibonacci number? 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233,377, 610, 987, 1597, 2584, 4181, 6765, 10946…

Additionally, how do you find the Fibonacci number?

The **Fibonacci Sequence** is the **series** of**numbers**: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, The next**number** is found by adding up the two **numbers** beforeit.

**Fibonacci Sequence**

- The 2 is found by adding the two numbers before it (1+1)
- The 3 is found by adding the two numbers before it (1+2),
- And the 5 is (2+3),
- and so on!

What does 1.618 mean?

The ratio, or proportion, determined by Phi(**1.618** …) was known to the Greeks as the“dividing a line in the extreme and **mean** ratio”and to Renaissance artists as the “Divine Proportion”It is also called the Golden Section, Golden Ratio and the Golden**Mean**.
