Complete the series, Logical Reasoning Questions and Answers

Here are ten sample questions for you:

Question 1: Complete the series: 2, 5, 10, 17, ___ Answer: 26 Explanation: The series follows a pattern where each term is the square of its position in the series minus 1. (1^2 - 1 = 0, 2^2 - 1 = 3, 3^2 - 1 = 8, 4^2 - 1 = 15). So, the next term would be 5^2 - 1 = 25 - 1 = 24.

Question 2: Complete the series: 3, 6, 9, 12, ___ Answer: 15 Explanation: The series follows an arithmetic progression with a common difference of 3. Each term is obtained by adding 3 to the previous term.

Question 3: Complete the series: 1, 1, 2, 3, 5, ___ Answer: 8 Explanation: The series is a Fibonacci sequence, where each term is the sum of the previous two terms.

Question 4: Complete the series: 7, 14, 28, 56, ___ Answer: 112 Explanation: The series follows a pattern of doubling the previous term to obtain the next term. (7 * 2 = 14, 14 * 2 = 28, 28 * 2 = 56)

Question 5: Complete the series: 10, 9, 17, 14, 26, ___ Answer: 21 Explanation: The series alternates between subtracting 1 and adding 8 to the previous term.

Question 6: Complete the series: 16, 25, 36, 49, ___ Answer: 64 Explanation: The series consists of perfect squares in ascending order.

Question 7: Complete the series: 2, 6, 12, 20, ___ Answer: 30 Explanation: The series adds consecutive even numbers to the previous term (2 + 4 = 6, 6 + 6 = 12, 12 + 8 = 20).

Question 8: Complete the series: 5, 10, 20, 40, ___ Answer: 80 Explanation: Each term is obtained by doubling the previous term.

Question 9: Complete the series: 4, 9, 16, 25, ___ Answer: 36 Explanation: The series consists of perfect squares in ascending order.

Question 10: Complete the series: 1, 4, 9, 16, ___ Answer: 25 Explanation: The series consists of perfect squares in ascending order.

Complete the series, Logical Reasoning Questions and Answers

Series 1: Number Sequence

Question: 2, 4, 8, 16, ?

Answer: The pattern here is that each term is being multiplied by 2. So, the next term in the sequence would be 16 * 2 = 32.

Series 2: Alphabet Sequence

Question: A, C, E, G, ?

Answer: The pattern here is that each letter is skipping one letter in the alphabet. So, the next letter in the sequence would be I.

Series 3: Fibonacci Sequence

Question: 1, 1, 2, 3, 5, ?

Answer: The pattern here is that each term is the sum of the previous two terms. So, the next term in the sequence would be 3 + 5 = 8.

Series 4: Geometric Shapes

Question: Triangle, Square, Pentagon, Hexagon, ?

Answer: The pattern here is that each shape has one more side than the previous shape. So, the next shape in the sequence would be a heptagon (7 sides).

Series 5: Odd-Even Pattern

Question: 1, 4, 9, 16, ?

Answer: The pattern here is that each term is a perfect square of consecutive positive integers. So, the next term in the sequence would be 25 (5 squared).

How to Solve Complete the series, Logical Reasoning Questions

Solving "Complete the Series" logical reasoning questions often involves identifying the pattern or rule governing the given sequence of numbers, letters, or symbols. Here's a step-by-step approach to help you tackle these types of questions:

  1. Analyze the Given Sequence: Carefully examine the sequence provided in the question. Identify whether it consists of numbers, letters, or symbols. Look for any apparent patterns or relationships between the elements.
  2. Look for Arithmetic or Geometric Progressions: If the sequence involves numbers, check if it follows an arithmetic progression (AP) or a geometric progression (GP). In an AP, each term is obtained by adding a constant value to the previous term. In a GP, each term is obtained by multiplying the previous term by a constant value.
  3. Identify Mathematical Operations: Observe if there are any mathematical operations being performed on the terms in the sequence, such as addition, subtraction, multiplication, or division. The pattern may involve applying these operations repeatedly.
  4. Check for Relationships between Adjacent Terms: Look for relationships between adjacent terms. For example, the difference between consecutive terms, the ratio between consecutive terms, or any other mathematical relationship.
  5. Consider Positional Patterns: Sometimes, the position of the terms in the sequence might hold significance. The pattern could be based on prime or odd/even positions.
  6. Look for Pattern Shifts: The pattern may change at a certain point in the sequence. Be vigilant for any shifts in the pattern, which could involve a different mathematical rule being applied from that point onward.
  7. Trial and Error: If you can't immediately identify a clear pattern, try different common number operations, ratios, or differences to see if any of them match the given sequence. Sometimes, trial and error can help reveal the underlying pattern.
  8. Elimination Method: If you have multiple options to choose from, plug in each option into the sequence and see if it follows the pattern. Eliminate options that don't match the pattern until you find the correct one.
  9. Use Logic and Intuition: Trust your logical reasoning and intuition. Sometimes, recognizing a pattern involves thinking creatively and considering possibilities that might not be immediately obvious.
  10. Practice, Practice, Practice: The more you practice solving these types of questions, the better you'll become at recognizing patterns and applying the appropriate techniques. Look for pattern-based puzzles, books, and online resources to improve your skills.

Remember that "Complete the Series" questions can vary widely in complexity, and some may have more intricate patterns than others. Developing a sharp eye for patterns and practicing regularly will enhance your ability to solve these types of logical reasoning questions effectively.
