Question
The table shows the number of different flower beds formed by a different number of paving slabs.
The number of paving slabs that will be needed for 8 flower beds is
- 26
- 30
- 34
- 38
Hint:
We are given a table with a number of flower beds and number of paving slabs. Number of different flower beds are formed using nun if different paving slabs. We are asked to find the number of paving slabs needed for 8 flower beds. We will find the relation between the number of paving slabs. Using the relation, we will find the required value.
The correct answer is: 34
If we observe the table, we will see that the number of paving slabs is increasing by 4 with increasing number of flower beds.
Using this rule, we will find the paving slabs needed for 8 flowers.
The paving slabs in one flower = 6
The paving slabs in two flowers = 6 + 4 = 10
The paving slabs in three flowers = 10 + 4 = 14
The paving slabs in four flowers = 14 + 4 = 18
The paving slabs in five flowers = 18 + 4 = 22
The paving slabs in six flowers = 22 + 4 = 26
The paving slabs in seven flowers = 26 + 4 =30
The paving slabs in eight flowers = 30 + 4 = 34
Therefore, the number of paving slabs needed to make for 8 flowers.
For such questions, we need to find the rule used to write the pattern.
