A pattern is a sequence of numbers, shapes, or other objects that follows a specific rule such as repeating, growing, or both. Number patterns can be repeating, growing, or a combination of both. Examples of number patterns include skip counting, repeating numbers, and growing numbers. Geometric patterns also follow specific rules with repeating shapes or letters. The document provides examples of number patterns and problems involving number patterns to solve.

2. WHAT IS A PATTERN?
A pattern is an ordered set of numbers, shapes or
other mathematical objects arranged according to a
rule.

3. NUMBER PATTERNS
Definition:
A number pattern is a sequence of
numbers that follows a specific rule
i.e.
 Repeating
 Growing
Examples:
 Growing Numbers
 Skip Counting
2,4,6,8,10,……..
5,10,15,20,25,…….
 Repeating Numbers
1 2 3 4 1 2 3 4 1 2 3 4……
 Repeating and Growing

4. GEOMETRIC PATTERNS
Definition:
A pattern that uses shapes or
letters that follows a specific
rule i.e.
Repeating patterns
Examples:
 Growing Numbers

5. NUMBER PATTERN
Observe the patterns and complete the following:
1 × 8 + 1 = 9
12 × 8 + 2 = 98
123× 8 + 3 = 987
1234 × 8 + 4 = 9876
12345 × 8 + 5 = 98765
123456 × 8 + 6 = 987654
1234567 × 8 + 7 = 9876543
12345678 × 8 + 8 = 98765432

6. NUMBER PATTERN
Find the sum of Consecutive Numbers:
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 = ……….
Solution::
8 + 0 = 8
1 + 7 = 8
2 + 6 = 8 1+2+3+4+5+6+7+8
3 + 5 = 8
4 + 0 = 4
Adding them all we can write
4 × 8 + 4= 32 + 4 = 36

7. WHAT IS A PATTERN?
Complete the following Pattern:
12345679 × 27 = 333333333
12345679 × 36 = 444444444
12345679 × 45 = 555555555
12345679 × 54 = 666666666
12345679 × 63 = 777777777
12345679 × 72 = 888888888
12345679 × 81 = 999999999

8. A little bug ate 135 flies in 5 days. Each day, it ate 10 more flies
than it did on the previous day. How many flies had the bug eaten
(A) After 3 days? (B) After 4 days?
Solution: Let the number of bugs eaten on 1st day be x
The number of bugs eaten on 2nd day = x+10
The number of bugs eaten on 3rd day = x+10+10 = x+20
The number of bugs eaten on 4th day = x+10+10+10 = x+30
The number of bugs eaten on 5th day = x+10+10+10+10 = x+40
Total bugs eaten = x +(x+10)+ (x+20)+ (x+30)+ (x+40)= 135
5x+ 100=135
5x=135-100
5x=35
x=35÷5=7
So, Bugs eaten after 3 days = 27 bugs
Bugs eaten after 4 days = 37 bugs
