Definition

What is it?

An increasing pattern is a sequence of numbers, shapes, or objects where each new item is larger or greater than the one before it. It shows a steady growth or upward trend as you move from one step to the next.

Simple Example

Quick Example

Imagine you are saving money in your piggy bank. On Monday, you put in ₹10. On Tuesday, you put in ₹15. On Wednesday, you put in ₹20. The amounts you are adding (₹10, ₹15, ₹20) form an increasing pattern because each day you add more than the previous day.

Worked Example

Step-by-Step

Let's find the next number in the increasing pattern: 5, 10, 15, 20, ___

1. Look at the first two numbers: 5 and 10. To go from 5 to 10, we add 5 (5 + 5 = 10).
---2. Look at the next pair: 10 and 15. To go from 10 to 15, we add 5 (10 + 5 = 15).
---3. Look at the next pair: 15 and 20. To go from 15 to 20, we add 5 (15 + 5 = 20).
---4. We can see a rule: each number is found by adding 5 to the previous number.
---5. To find the next number after 20, we add 5 to 20.
---6. 20 + 5 = 25.
---The next number in the pattern is 25.

Why It Matters

Understanding increasing patterns helps us predict future trends and make smart decisions. Scientists use them to study population growth, economists use them to track market prices, and even data analysts use them to see how app usage is growing. This skill is key in many exciting careers!

Common Mistakes

MISTAKE: Confusing increasing patterns with decreasing patterns. | CORRECTION: In an increasing pattern, numbers always get bigger. In a decreasing pattern, numbers always get smaller.

MISTAKE: Only looking at the first jump and assuming it's the rule for the whole pattern. | CORRECTION: Always check at least two or three steps in the pattern to confirm the rule (e.g., adding 2, multiplying by 3, etc.) before predicting the next term.

MISTAKE: Not identifying the 'rule' of the pattern (e.g., what is being added or multiplied). | CORRECTION: First, find the difference or ratio between consecutive terms to figure out the exact operation that makes the pattern increase.

Practice Questions

QUESTION: What is the next number in the pattern: 2, 4, 6, 8, ___? | ANSWER: 10

QUESTION: Find the missing number: 3, 6, ___, 12, 15 | ANSWER: 9

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

MCQ

Quick Quiz

Which of these is an increasing pattern?

10, 8, 6, 4

5, 10, 15, 20

7, 7, 7, 7

25, 20, 15, 10

The Correct Answer Is:

Option B (5, 10, 15, 20) is an increasing pattern because each number is greater than the previous one (increasing by 5). Options A and D are decreasing patterns, and Option C is a constant pattern.

Real World Connection

In the Real World

In India, increasing patterns are everywhere! Think about the number of followers your favorite cricketer gains on Instagram each month – that's an increasing pattern. Or how the price of petrol has been changing over the years – often an increasing trend. Even the number of users on payment apps like Google Pay or PhonePe shows an increasing pattern as more people adopt digital transactions.

Key Vocabulary

Key Terms

PATTERN: A repeated arrangement of numbers, shapes, or objects. | SEQUENCE: A set of numbers or objects arranged in a specific order. | TREND: A general direction in which something is developing or changing. | GROWTH: The process of increasing in size, quantity, or importance.
