What is it?

What Comes Next in Logic is about finding the pattern or rule in a sequence of items and then predicting the next item. It's like being a detective and figuring out what happens next based on what you've seen before. This concept helps us understand order and prediction.

Simple Example

Quick Example

Imagine you see a traffic light change from Red to Yellow, then Yellow to Green. What comes next? You know it will be Red again, because that's the usual pattern. This is a simple example of 'what comes next' in everyday life.

Worked Example

Step-by-Step

Let's look at this sequence of numbers: 2, 4, 6, 8, ?

1. First, observe the numbers: 2, 4, 6, 8.
---2. Try to find the relationship between each number and the next. How do we get from 2 to 4? We add 2. How do we get from 4 to 6? We add 2. How do we get from 6 to 8? We add 2.
---3. The pattern is 'add 2' to the previous number.
---4. To find the next number, apply this pattern to the last number, which is 8.
---5. So, 8 + 2 = 10.
---The next number in the sequence is 10.

Why It Matters

Understanding 'what comes next' helps us predict outcomes in many subjects, from Maths to Science. It's crucial for careers like software development, where you predict how a program will run, or in data science, where you predict future trends. Even doctors use it to predict how a patient's health might change.

Common Mistakes

MISTAKE: Guessing the next item without finding the actual rule. | CORRECTION: Always look for a consistent pattern or rule that connects all the given items, not just the first few.

MISTAKE: Assuming the pattern is simple addition or subtraction when it could be multiplication, division, or a combination. | CORRECTION: Test different types of operations (add, subtract, multiply, divide) or even changes in shape/colour if it's a visual pattern.

MISTAKE: Focusing only on the last two items to find the pattern. | CORRECTION: Examine the entire sequence from the beginning to ensure the rule you find applies consistently to all elements.

Practice Questions

Try It Yourself

QUESTION: What comes next in this sequence: 10, 20, 30, 40, ? | ANSWER: 50

QUESTION: Look at these shapes: Circle, Square, Circle, Square, Circle, ?. What comes next? | ANSWER: Square

QUESTION: Find the next number: 1, 3, 6, 10, 15, ? | ANSWER: 21 (The pattern is adding 2, then 3, then 4, then 5, so next add 6)

MCQ

Quick Quiz

What is the next letter in the sequence: A, C, E, G, ?

The Correct Answer Is:

The pattern is skipping one letter each time (A to C skips B, C to E skips D, etc.). So after G, skipping H leads to I.

Real World Connection

In the Real World

Forecasting the weather is a great example! Meteorologists look at patterns in temperature, wind, and rain over days and weeks. By understanding 'what comes next' in these weather patterns, they can predict if it will rain tomorrow or if there will be a heatwave, helping farmers and people plan their day.
