What is it?

Finding 'What is Next?' means identifying the next item or step in a pattern, sequence, or series. It involves observing the given information, understanding the rule or logic behind it, and then applying that rule to predict the upcoming element.

Simple Example

Quick Example

Imagine you are watching a traffic light. First it's Red, then Yellow, then Green. What comes next? It's Red again! You saw the pattern (Red -> Yellow -> Green -> Red) and predicted the next colour.

Worked Example

Step-by-Step

Let's find the next number in this series: 2, 4, 6, 8, ?

1. Observe the numbers: 2, 4, 6, 8.
---
2. Look for a pattern or rule. How do we get from 2 to 4? We add 2 (2 + 2 = 4).
---
3. Check if this rule applies to the next numbers: From 4 to 6? Yes, 4 + 2 = 6. From 6 to 8? Yes, 6 + 2 = 8.
---
4. The rule is to add 2 to the previous number.
---
5. Apply the rule to the last number given: 8 + 2 = 10.
---
Answer: The next number in the series is 10.

Why It Matters

Understanding 'What is Next?' is fundamental to Logic, Computing, and Maths. It helps us predict outcomes and make smart decisions. This skill is crucial for careers in software development, data science, and even in everyday problem-solving.

Common Mistakes

MISTAKE: Jumping to conclusions with only one or two steps of a pattern | CORRECTION: Always check the pattern across multiple steps to confirm the rule before predicting the next item.

MISTAKE: Assuming the pattern is always addition or subtraction | CORRECTION: Patterns can also involve multiplication, division, squares, cubes, or even alternating rules. Look for all possibilities.

MISTAKE: Getting confused by complex-looking numbers and giving up | CORRECTION: Break down the problem. Look at the difference between numbers, then the difference between those differences. Sometimes patterns are hidden layers deep.

QUESTION: Find the next number: 5, 10, 15, 20, ? | ANSWER: 25

QUESTION: What comes next: 1, 4, 9, 16, ? (Hint: Think about multiplication) | ANSWER: 25 (These are square numbers: 1x1, 2x2, 3x3, 4x4, 5x5)

MCQ

Quick Quiz

Which option correctly identifies the next item in the sequence: Mango, Apple, Mango, Apple, ?

Banana

Apple

Mango

Orange

The Correct Answer Is:

The pattern is an alternating sequence of Mango and Apple. Since the last item was Apple, the next item in the sequence must be Mango.

Real World Connection

In the Real World

When you use a music streaming app like Spotify or JioSaavn, the 'recommended songs' feature often uses algorithms that predict 'what's next' based on your listening history. Similarly, weather apps predict the next day's temperature by finding patterns in past weather data.

Key Terms

SEQUENCE: An ordered list of items | PATTERN: A repeated arrangement or design | LOGIC: The process of reasoning and drawing conclusions | PREDICT: To say or estimate what will happen in the future
