Summary

This video script provides a comprehensive guide on solving number series questions often encountered in job tests. It explains how to identify patterns in sequences using addition, subtraction, multiplication, and division. The script breaks down various series with clear examples, including simple arithmetic sequences and more complex patterns involving multiple operations. The goal is to help viewers develop the skills to recognize and solve number series efficiently, preparing them for typical job test challenges.

Takeaways

• 😀 Identifying number series patterns is crucial for job test preparation.
• 😀 Simple arithmetic operations like addition, subtraction, multiplication, and division are the foundation for many number series.
• 😀 Some number series patterns involve increasing or decreasing a fixed number, such as adding or subtracting a constant value.
• 😀 Recognizing twin numbers or repeating patterns can help predict the next numbers in a series.
• 😀 Multiplication and division can be used to form exponential patterns, such as multiplying by 3 in a series.
• 😀 Complex number series often involve a combination of operations like alternating addition and subtraction or multiplying and dividing.
• 😀 Some patterns are tiered, meaning the difference between consecutive numbers changes incrementally (e.g., adding 1, 2, 3, 4, etc.).
• 😀 Pay attention to series that alternate between addition and subtraction with fixed values (e.g., +3, -1).
• 😀 It’s important to practice different patterns, as job tests may use various combinations of arithmetic and geometric operations.
• 😀 Recognizing the structure of a series early allows you to predict the next numbers, making it easier to complete job test questions.

Q & A

What is the pattern in the first number series 4, 8, 12, 16, 20, 24?

The pattern is an addition of 4. Each number is increased by 4 from the previous number.

How do we solve the series 16, 8, 4, 2, 1/2?

Each number is divided by 2. So, 16 ÷ 2 = 8, 8 ÷ 2 = 4, 4 ÷ 2 = 2, and 2 ÷ 2 = 1.

What is the pattern in the series 17, 22, 27, 32, 37, 42?

The pattern is an addition of 5. Each number is increased by 5 from the previous number.

In the series 5, 6, 8, 11, 15, 20, how do we determine the next numbers?

The pattern involves increasing the difference by 1. From 5 to 6 is +1, from 6 to 8 is +2, from 8 to 11 is +3, from 11 to 15 is +4, and from 15 to 20 is +5. Therefore, the next number is 20 + 6 = 26, and the following number is 26 + 7 = 33.

How does the series 65, 58, 51, 44, 30, 23, 6, 12 work?

The pattern involves subtracting 7 from each number. 65 - 7 = 58, 58 - 7 = 51, 51 - 7 = 44, and so on.

What is the method used to solve the series 12, 19, 16, 13, 11?

This series has two patterns. The first pattern alternates between subtracting 3 and subtracting 2. 12 - 3 = 9, 9 - 3 = 6. The second pattern is just the number 1 remaining unchanged.

In the series 10, 10, 7, 7, how do we determine the next numbers?

The pattern alternates between subtracting 3 and adding 3. The numbers decrease by 3 (10 to 7), and then repeat with the next pair.

How do we solve the pattern in the series 1/3, 1, 3, 9, 27, 81?

The pattern involves multiplying each number by 3. 1/3 × 3 = 1, 1 × 3 = 3, 3 × 3 = 9, and so on.

What is the pattern in the series 21, 19, 17, 15, 13, 11?

The pattern involves subtracting 2 from each number. 21 - 2 = 19, 19 - 2 = 17, and so on.

In the series 7, 12, 17, 22, 27, how do we determine the next numbers?

The pattern involves adding 5 to each number. 7 + 5 = 12, 12 + 5 = 17, 17 + 5 = 22, and so on.
