## What is series formula?

The series of a sequence is the sum of the sequence to a certain number of terms. It is often written as **S _{n}**. So if the sequence is 2, 4, 6, 8, 10, … , the sum to 3 terms = S

_{3}= 2 + 4 + 6 = 12. The Sigma Notation.

## How do you find the pattern in a number series?

Identify the pattern of the sequence by **finding the difference between two consecutive terms**. 44 – 36 = 8 and 20 – 12 = 8. The pattern of the sequence is, therefore, the addition of 8 to the preceding term.

## What is series and sequence?

What does a Sequence and a Series Mean? **A sequence is defined as an arrangement of numbers in a particular order.** **On the other hand, a series is defined as the sum of the elements of a sequence**.

## WHAT IS series and its example?

What exactly is a series? Actually, a series in math is simply **the sum of the various numbers or elements of the sequence**. For example, to make a series from the sequence of the first five positive integers 1, 2, 3, 4, 5 we will simply add them up. Therefore 1 + 2 + 3 + 4 + 5 is a series.

## What kind of sequence is 1234?

This is an **arithmetic sequence** since there is a common difference between each term.

## What is the formula of sequence?

An arithmetic sequence is a sequence in which the difference between each consecutive term is constant. An arithmetic sequence can be defined by an explicit formula in which **a _{n} = d (n – 1) + c**, where d is the common difference between consecutive terms, and c = a

_{1}.

## What is two stage type series?

The Two Stage Type Series is **a series in which the difference between consecutive terms forms a series of its own**. In such series, we have a parent series whose terms have a regular difference between them. The difference between each consecutive term of the parent series forms an arithmetic progression of its own.

## What is square series?

Perfect square series is **an arrangement of numbers in a certain order where each numbers are square of a number**. So, in that series of numbers some numbers are missing. You need to observe and find the missing number of that series of numbers.
