What is it?

A growing pattern in numbers is a sequence where each number is larger than the one before it, following a specific rule. This rule tells us how much to add or multiply to get the next number in the pattern.

Simple Example

Quick Example

Imagine you save money in your piggy bank. On Monday, you put in ₹5. On Tuesday, you put in ₹10. On Wednesday, you put in ₹15. This is a growing pattern because you are adding ₹5 each day.

Worked Example

Step-by-Step

Let's find the next two numbers in the pattern: 2, 4, 6, 8, ___, ___.

STEP 1: Look at the first two numbers: 2 and 4. What did we do to 2 to get 4? We added 2 (2 + 2 = 4).
---
STEP 2: Check this rule with the next pair: 4 and 6. Did we add 2? Yes, 4 + 2 = 6.
---
STEP 3: Check again: 6 and 8. Did we add 2? Yes, 6 + 2 = 8.
---
STEP 4: The rule is to add 2 to the previous number.
---
STEP 5: To find the first missing number, add 2 to 8: 8 + 2 = 10.
---
STEP 6: To find the second missing number, add 2 to 10: 10 + 2 = 12.
---
ANSWER: The next two numbers are 10 and 12.

Why It Matters

Understanding growing patterns is super important in Maths, Computing, and even AI! It helps us predict future events, like how many people might use a new app next month or how a robot can learn to move. This skill is useful for data scientists and software developers.

Common Mistakes

MISTAKE: Students sometimes guess the next number without finding the rule. | CORRECTION: Always find the rule (what is added or multiplied) first, then apply it to find the next numbers.

MISTAKE: Confusing a growing pattern with a shrinking pattern (where numbers get smaller). | CORRECTION: Remember, in a GROWING pattern, numbers always increase.

MISTAKE: Only checking the rule for the first two numbers and assuming it applies to all. | CORRECTION: Check the rule between at least two or three pairs of numbers to be sure it's consistent.

QUESTION: A plant grows 2 cm in the first week, 4 cm in the second, and 6 cm in the third. If this pattern continues, how much will it grow in the fifth week? | ANSWER: 10 cm (The pattern is +2 cm each week. Week 1: 2, Week 2: 4, Week 3: 6, Week 4: 8, Week 5: 10)

MCQ

Quick Quiz

Which of these is a growing pattern?

10, 8, 6, 4

2, 4, 6, 8

5, 5, 5, 5

100, 50, 25, 12.5

The Correct Answer Is:

Option B (2, 4, 6, 8) is a growing pattern because each number increases by 2. Options A and D are shrinking patterns, and Option C is a repeating pattern.

Real World Connection

In the Real World

Growing patterns are everywhere! Think about how your mobile data usage might increase each month if you watch more videos. Or how the number of passengers in an auto-rickshaw queue might grow during peak hours near a railway station. Even how the population of a city in India grows over years follows patterns.

Key Vocabulary

Key Terms

PATTERN: A set of numbers or objects that repeat or change in a predictable way. | SEQUENCE: An ordered list of numbers. | RULE: The operation (like add or multiply) that tells how to get the next number in a pattern. | INCREASE: To get larger in amount or number.

Great job understanding growing patterns! Next, you should explore 'Shrinking Patterns' to see how numbers can decrease following a rule. This will help you understand different types of number sequences even better.
