## How do you write a general term for a sequence?

General Term An arithmetic sequence is a linear function. Instead of y=mx+b, we write an=dn+c where d is the common difference and c is a constant (not the first term of the sequence, however). A recursive definition, since each term is found by adding the common difference to the previous term is ak+1=ak+d.

## How would you describe 3x 2 as an expression?

Answer: In each of the terms 3x 2 and 7x, x is a variable, and in both terms, we are multiplying a number by the variable. In the first term, 3x 2, 3 is being multiplied by the variable, so 3 is a coefficient. In the second term, 7x, 7 is being multiplied by the variable, so 7 is a coefficient.

## What is the example of sequence in English?

The order that the things are in matters. For example, both (Blue, Red, Yellow) and (Yellow, Blue, Red) are sequences, but they are not the same. Sequences made up of numbers are also called progressions. There are two kinds of sequences.

## What is general rule of a sequence?

If the rule is to add or subtract a number each time, it is called an arithmetic sequence. If the rule is to multiply or divide by a number each time, it is called a geometric sequence. Each number in a sequence is called a term.

## What does general rule mean?

General rule is a rule that is applicable to a class of cases or circumstances. It can also be formal order or direction made by a court, as for governing the procedure of the court or a general norm mandating or guiding conduct or action in a given type of situation.

## How do you define 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 series and sequence?

In mathematics, a sequence is a list of objects (or events) which have been ordered in a sequential fashion; such that each member either comes before, or after, every other member. A series is a sum of a sequence of terms. That is, a series is a list of numbers with addition operations between them.

## What is the formula of sequence?

Sequence and Series Formulas

Arithmetic Progression | |
---|---|

Sequence | a, a+d, a+2d,……,a+(n-1)d,…. |

Common Difference or Ratio | Successive term – Preceding term Common difference = d = a2 – a1 |

General Term (nth Term) | an = a + (n-1)d |

nth term from the last term | an = l – (n-1)d |

## What are the different ways of writing an expression?

This section describes the types of expressions that you can write in Maintain:

- Numeric. Use a numeric expression to perform a calculation on numeric constants or variables.
- Date and time. Use a date and time expression to perform a calculation that involves dates and/or times.
- Character.
- Logical.
- Conditional.

## What is a term number in a 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). In the sequence, each number is called a term. The number 5 has first position, 15 has second position, 25 has third position and so on.
