## What is a set of numbers which is written in a special order based on definite rule?

In mathematics, a sequence is an enumerated collection of objects in which repetitions are allowed and order matters. Like a set, it contains members (also called elements, or terms). The number of elements (possibly infinite) is called the length of the sequence.

**What do you call to a number in a sequence?**

Each number in a sequence is called a term . Each term in a sequence has a position (first, second, third and so on). For example, consider the sequence {5,15,25,35,…} In the sequence, each number is called a term.

**What do you call a set or list of numbers arranged in a definite order?**

Definition (Sequence): A set of numbers arranged in a definite order according to some definite rule (or rules) is called a sequence. Each number of the set is called a term of the sequence. A sequence is called finite or infinite according as the number of terms in it is finite or infinite.

### What is a letter that represents a number?

Variables and Constants In algebra, symbols (usually letters) are used to represent numbers. A variable is a letter or symbol used as a placeholder for an unknown value. What’s a Variable? A constant can be a letter or a symbol that represents a fixed number.

**How do you describe a sequence?**

A sequence is an ordered list of numbers . The three dots mean to continue forward in the pattern established. Each number in the sequence is called a term. In the sequence 1, 3, 5, 7, 9, …, 1 is the first term, 3 is the second term, 5 is the third term, and so on.

**What is Fibonacci sequence formula?**

Fibonacci numbers are a sequence of whole numbers: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, This infinite sequence is called the Fibonacci sequence. Here each term is the sum of the two preceding ones, starting from 0 and 1….What is Fibonacci Sequence?

F0 = 0 | F10 = 55 |
---|---|

F7 = 13 | F17 = 1597 |

F8 = 21 | F18 = 2584 |

F9 = 34 | F19 = 4181 |

## What set of numbers shows a pattern?

Number pattern is a pattern or sequence in a series of numbers. This pattern generally establishes a common relationship between all numbers. For example: 0, 5, 10, 15, 20, 25.
