## What is the expression of sequence?

A sequence is a list of numbers in a certain order. 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 above sequence, the nth term an can be calculated using the equation an=10n−5 .

What is a sequence example?

A sequence is an ordered list of numbers . 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 sequence in computer?

Sequence, the order that commands are executed by a computer, allows us to carry out tasks that have multiple steps. In programming, sequence is a basic algorithm: A set of logical steps carried out in order.

### When to use ” please let me know ” in a sentence?

— I can check that for you tomorrow morning. — Yes, please let me know. This is a perfectly fine way to respond to that statement. Adding an explicit time frame (“Please let me know as soon as you find out”) is permissible and may be clearer, but it’s not required. Let me know. Let me jump. Let me ride. Listen. Go.

What do you call each number in a sequence?

Each number in the sequence is called a term (or sometimes “element” or “member”), read Sequences and Series for a more in-depth discussion.

How to find a missing number in a sequence?

Each number in the sequence is called a term (or sometimes “element” or “member”), read Sequences and Series for a more in-depth discussion. To find a missing number, first find a Rule behind the Sequence.

## What does XN-2 mean in sequence math?

It means “the previous term” as term number n-1 is 1 less than term number n. And xn-2 means the term before that one. Let’s try that Rule for the 6th term: So term 6 equals term 5 plus term 4. We already know term 5 is 21 and term 4 is 13, so:
