What does a Pattern Mean?
A pattern is a design or arrangement that repeats continuously. Let us identify the rule of the pattern of changing figures
Number Patterns
Did you observe the pattern in the above figure? Observing the pattern we can find the rule for given pattern. The figures show the total of the numbers up to “n”.
In the first figure, we can see that there are three dots. The 1st layer has = 1 + 2 = 3 dots
In the second figure, we can see that there are six dots. The 2nd layer has = 1 + 2 + 3= 6 dots
The third figure shows six layers and has = 1 + 2 + 3 + 4 = 10 dots
In the last figure, we can see four layers and the total numbers of dots are = 1 + 2 + 3 + 4 + 5 = 15 dots
Patterns of Figures
Number Patterns
Observe the figure given above. In the first figure, we can see that there are 4 triangles and 1 square. The second figure shows 6 triangles and 2 squares. In the third figure, we can see 8 triangles and 3 squares. The last figure has 10 triangles and 4 squares. Now can you guess the next figure?
Observing the above figures it is understood that the next figure will have 5 squares and 12 triangles. Let’s take one more example – identify the figure that will continue the series when the first and last figure is the same.
Number Patterns
Can you answer this question? In this type of questions, a picture series will be given such that the first and last figures are the same. Now we need to find the figure from the given alternatives that will continue the series.
From the above figure, we can say that the first and last figures being the same, the figure to appear next will be the same as the second figure in the given question. Thus, the answer figure will be the same as the second figure.
Number Patterns
Patterns can also be very commonly observed in numbers (series and sequences). Here are some square numbers follows a pattern:
11 = 1
111 = 121
Further
1111 = 12321
11111 = 12343211
Further
111112 = 123454321
1111112 = 1234564321 and so on.
Observe the Number Patterns
Find the next two term in the series 0, 5, 19, 15,…
Solution: We can see that in the series each of the previous numbers is added to 5 to get the new number hence the next numbers will be 15 + 5 = 20 and so 20 + 5 = 25
