Here, first three patterns are given and we have to find next three patterns.
We can see in given first three patterns, there is an increment by 1 box in row as well as column.
So, we can find pattern 4,5 and 6 by increasing single box in row as well as column.
Therefore, the next three patterns are shown below :-
Page 235 Problem 2 Answer
Here, first three terms are given. Now, we have to find next three terms.
A box is increased by 1in middle column as well as one row line is also increased by 1in each pattern.
Therefore, in pattern4,5 and 6 one box in middle column and one row line is increased.
So, the next three patterns are shown below:-
Page 236 Problem 3 Answer
Here, first four terms are given. Now, we have to find next three terms
Here, we can see that in pattern1,2,3and 4 the number of boxes are 1,3,5 and 7.
From this it is clear that the number of boxes present in each pattern is increased by2.
Therefore, using this we can find next three terms pattern5,6and7.
The next three pattern are as below :-
Pattern5
Pattern6
Pattern7

Given that: 6,13,27,55,……
To do: Find the next number in the given series.
Since,
The given series is
13−6=7=7……………………(1)
27−13=14=7×2…………………….(2)
55−27=28=14×2………………(3)
x−55=28×2………………….(4)
So,x=111
Therefore, the next number in the given series is, 111
