Ace Your Bank Exam with These Missing Number Series Strategies

A missing number series is a sequence of digits where one or more elements are omitted. These are some common questions in banking exams where the main task is determining the missing digits based on the given sequence. Developing problem-solving and mathematical skills is crucial for tackling these questions effectively.

A systematic strategy is essential to identify the underlying pattern in the missing number series for the bank exam. Mastering the techniques can significantly enhance aspirants’ quantitative aptitude scores. This article provides comprehensive techniques and examples to solve these problems efficiently. Equip yourself with the strategies and confidently boost your exam performance.

Minute Screening of the Sequence

The first step in solving such problems is to screen the sequence minutely. Look at the sequence carefully and observe any apparent difference between the digits. The orders can be based on addition, subtraction, multiplication, division, or even a combination of these operations. Sometimes, it might involve more complex operations like squares, cubes, or factorials. For example, consider the series 2, 4, 8, 16, ?. The pattern here is that each is multiplied by 2 to get the next digit.

Checking Whether It Is Increasing or Decreasing

The next step after screening is to determine whether the numbers are increasing or decreasing. This step is crucial to narrow down the possible sequence. An increasing order might involve addition or multiplication, while a decreasing one might involve subtraction or division. For instance, if the series is 20, 15, 10, 5, and ? – you can quickly notice that it is decreasing. Here, each digit is subtracted by 5 to get the next one.

Tracking the Rate of Increase or Decrease

After identifying whether the series is increasing or decreasing, you should track the rate of this change. The difference between consecutive numbers can change progressively. Take this example: 3, 6, 11, 18, ?. Initially, it might seem confusing, but notice the differences between the digits: 3, 5, 7. The differences are increasing by 2 each time.

Estimating the Difference and Finding The Answer

If you can not immediately see a sequence, try estimating the differences. Write down the differences and see if they form a pattern themselves. This method is beneficial for more complex orders that are not immediately obvious. For example, in the series 5, 10, 20, 35, and ?, the differences are 5, 10, and 15. Here, the differences increase by 5 each time.

Final Checking of the Orders

After calculating the missing digit, it is essential to check if all the numbers in the question follow the same sequence or difference. This verification step ensures that your identified order is correct and the series is consistent. Additionally, revisit any assumptions made during the analysis to confirm their validity. By thoroughly reviewing each element, you can confidently conclude that the pattern is accurate and reliable.

Practice Makes Perfect

The key to mastering such tricky math-based questions is practice, which is paramount to earning good grades. The more you practice, the better you will spot patterns quickly and accurately. Use online resources like easily downloadable PDFs with questions of all levels to hone your skills. Comparing your answers with the given solutions in the PDFs provides valuable insights and different perspectives on solving these problems. Consistent practice and engagement with a community of learners will significantly enhance your proficiency.

Mastering the missing number series for the bank exam trains your mind to analyze patterns and apply logic, ultimately sharpening your calculation abilities for success. With structured strategies, you will be well-equipped to tackle this section and move closer to completing your bank exam. Consistent practice is the key; keep solving those number series, and your confidence and accuracy will soar.
