Number series reasoning

Number series questions in Numbers in a series are described as ‘terms’, and they are presented in a sequence with gaps – the candidate must find the missing term(s) to complete the question. As these are part of numerical reasoning tests, the answers are usually presented in a multiple-choice format. In the sequence, there are typically between four to seven visible numbers, and to find the missing elements the candidate needs to find the specific logical rule or pattern that links the series, and apply that to the missing numbers. Number series questions are based on rather simple mathematical rules. They are difficult because the pattern may be less obvious, rather than it being based on complicated arithmetic. Different forms of number series questions There are several types of number series questions, and the types are based on what logic connects the numbers in a sequence. Arithmetic sequence The relationship between terms in an arithmetic number series is based on adding, subtracting, or a combination of both operations. The most basic version of this is 1, 2, 3, 4, 5 __ where the next number would be six because the rule is to add one to the last digit. Geometric sequence In a similar way to arithmetic sequences, geometric sequences contain numbers that share a rule based on multiplication or division. Mixed sequence A mixed sequence describes the relationship between terms as being based on more than one rule. This can make finding the right answer more complicat...

Reasoning Ability section is one of the important subjects of all competitive exams. Of all the topics covered under the section, Number or Letter series is asked for 3-5 marks, which seems to be valuable! So, knowing all the patterns asked in this topic will really help the candidate to master the topic. And thus save the marks! In this article let us go through a different number series questions and also download a free PDF with questions related to this topic. What is meant by Number Series? In this question, a series of numbers or letters, following a specific pattern will be given. But a number or letter at some position will be missing or wrongly marked. Candidates have to identify that number and fill the gap or identify the wrong number. For the same, the simplification part has to be strong and should be able to guess the pattern from the numbers. The series can be of differences, addition, product, squares and cubes, miscellaneous series. Also, series can be like even number, an odd number, prime number series. Squares and cubes are easily identifiable and scorable among the series. The combination of all these can also be expected. For letter series, candidates should know the order and rank or position values of each alphabet, which will surely help to solve the series. One can solve the problem from either left to right or vice-versa. Let us practice questions with an example each. Sample Questions 1. 9, 8,10, 9, 11, 10, ………. Solution: 12. The series is havin...

Answer: a. TZ Explanation: A B C D E F G H I J K L M N O P Q R S T U V W X Y Z Here the next alphabet skips alphabets in increasing order of 0, 1, 2, 3, etc. • After E, 0 alphabets skipped. So, we get F which is immediately next. • After F, 1 alphabet skipped. So, we skip G which is next and get H. • After H, 2 alphabets skipped. So, we skip I J and get K. • After K, 3 alphabets skipped. So, we skip L M N and get O. • After O, 4 alphabets skipped. So, we skip P Q R S and get T. • After T, 5 alphabets skipped. So, we skip U V W X Y and get Z. 2. Find the next in the sequence 5, 21, 69, 213, 645, ? a. 1935 b. 1815 c. 1941 d. 1290 Answer: b.

How to Solve Number Series: Example Questions & Tips – 2023 Numerical sequence questions test your ability to recognize patterns and manipulate numbers using a variety of mathematical functions. Whether you’ll have to fill in the missing numbers or rearrange the terms according to the rule, these series number tests will keep you on your toes. Number series questions generally appear on What Are Number Series? A number series is a list of numbers whose placement is determined according to a certain rule. That rule may be as simple as adding or multiplying by one factor, or it may involve a complex series of steps. Some series even require two separate rules, which are employed alternatingly. How to Solve Series Questions? Your job is to determine the series’ rule by analyzing the numbers given to you. Sometimes the answer will be self-evident, but most of the time it won’t be. If your only method of solving problems is trial-and-error, you’ll waste a lot of time guessing. Thankfully, series questions follow predictable patterns. If you’re familiar with the five most common patterns for number series, then you’ll quickly be able to eliminate possibilities until you come to the correct answer. Simple Arithmetic Number Series In an arithmetic number series, each number either increases or decreases by the same amount each time. These series are relatively easy to spot. You should always check to see whether the series is increasing or decreasing by a constant factor before mo...
