The Arithmetic number series is the key theme of mathematics and is often asked in the quantitative and reasoning section of various SSC & Railways Exam. In the Arithmetic number series questions, the series is based on numerical sequences that follow logical patterns based on basic arithmetic concepts. We must then detect the idea by following the same logic and predicting the next number. Work alone will help you master it.
Competitive exams are becoming the main segment of young people’s lives who have graduated and are ready to get a decent job. It’s undoubtedly difficult to succeed in these exams, but it’s easier if you know the key topics and the preparatory methods. You need an explicit command over both parts when appearing in these studies.
A sequence constructed from numbers is the Arithmetic number series. We will need to detect the rules that occur in creating a number set in the number series questions. These series are of several sorts, and so are the problems that may emerge from these topics.
It consists of a sequence in which a constant number is added/subtracted to the previous term to achieve the next term. Example: 4, 9, 14, 19, 24, 29, 34, where 5 is the number to be added to obtain the current number. Now, we have a 2,3,4,5 arithmetic series.
1) A numerical sequence query [example] can be answered in more than one way.
Take the data between each term: a sequence can consist of two alternating sequences or take the data of several combined transactions, as described above.
2) Search for the difference between terms: if you cannot find a law, search for a distinction between consecutive terms – an independent sequence can be formed.
To speed up the response, use the multiple choices.
3) Don’t be scared by the calculation. To find the correct answer, often, you don’t need complete calculations.
4) Practise using a calculator(for calculator uses): Learn how to use different advanced formulas or operations, including exponents, square roots, factorials, memory, etc., apart from basic arithmetic operations.

5) Know how to do mathematical operations like fundamental arithmetic, fractions, decimals, exponents, etc

Gradeup provides some incredible benefits:
1) What is the series number?
A serial number is a unique integer assigned incrementally or sequentially to an object, to uniquely identify it. Serial numbers do not have to be purely binary. They may contain letters and other indications in typography or may consist entirely of a string of characters.
2) What is the series formula?
The series of a sequence is the sum of the sequence to a certain number of terms. It is often written as Sn. So if the sequence is 2, 4, 6, 8, 10, ... , the sum to 3 terms = S3 = 2 + 4 + 6 = 12. The Sigma Notation, the Greek capital sigma, written as ‘S’, is usually used to represent the sum of a sequence.
3) What is the missing number?
Missing numbers are the numbers that are missed in the given series of numbers with similar differences among them. The process of writing the missing numbers is termed as finding similar changes among those numbers and filling their missing values in their specific series and places.
4) What is the sum of a series?
The sum of the terms of a sequence is called a series. If a sequence is arithmetic or geometric there are formulas to find the sum of the first n terms, denoted Sn, without actually adding all of the terms.
5) How do you answer a series number?
By taking the difference between consecutive pairs of numbers, which form a logical sequence, you will find the correct answer in the number set. The differences between successive pairs of numbers are 1,2, 4, 8, 16, and 32 in this case. So, 64 has to be the next gap.
