In this blog, we will go over the fundamentals of Series Completion Reasoning problems, as well as the types of questions asked in previous year exams and how to approach them. This will help you clear your basics and answer these Series Completion Reasoning questions.

What is Series Completion?

Series completion entails identifying the hidden pattern or rule governing a sequence and using that pattern to predict the next element. These sequences can encompass numerical patterns, alphabetical patterns, or a combination of both. 

Series patterns come in various forms, each requiring a distinct approach. Some common types include:

• Arithmetic Series: In this type, the difference between consecutive terms follows a constant pattern. For instance, 2, 4, 6, 8, 10 is an arithmetic series with a common difference of 2.
• Geometric Series: Here, the ratio between consecutive terms remains constant. For example, 3, 6, 12, 24, and 48 is a geometric series with a common ratio of 2.
• Alphabetical Series: In alphabetical series completion, you identify the pattern among letters, considering their positions in the alphabet. For instance, A, C, E, G, I follow a pattern of skipping one letter in the alphabet.
• Mixed Series: These series combine numerical and alphabetical patterns. Solving them requires simultaneously recognising both types of patterns.

Tips for Solving Series Completion Questions

Here are some tips for solving completing questions:

• Analyse the Given Series: Begin by carefully analyzing the provided series. Look for numerical or alphabetical patterns and try to identify any deviations from these patterns.
• Identify the Series Type: Determine whether the series follows an arithmetic, geometric, alphabetical, or mixed pattern. This identification is crucial for making accurate predictions.
• Look for Deviations: Pay close attention to any irregularities or deviations in the series, as they may hold the key to understanding the pattern.
• Apply Logic: Use logical reasoning to deduce the pattern’s rules. Ask yourself questions like, “What is changing from one term to the next?” or “Is there a consistent mathematical operation occurring?”
• Practice Regularly: Series completion is a skill that improves with practice. The more series of patterns you explore, the better you become at recognizing and solving them.
