Answer 1

Before, finding the answer. Let's find out we can find the answer.

• In this question, we are asked to find the rule of the given pattern.

__________________________

Given :

• 1,5,9,13,17

To find :

• Rule

Solution :

Data = 1,5,9,13,17

We see that,

1 + 4 = 5

5 + 4 = 9

9 + 4 = 13

13 + 4 = 17

• Rule = Here, the rule is we have to add 4 to numbers.

-----------------------

Given :

• 2,6,18,54,162

To find :

• Rule

Solution :

We see that,

2 × 3 = 6

6 × 3 = 18

18 × 3 = 54

54 × 3 = 162

• Rule = Here, the rule is we have to multiply the number by 3.

------------------------

Given :

• 39,37,35,33,31

To find :

• Rule

Solution :

We see that,

39 - 2 = 37

37 - 2 = 35

35 - 2 = 33

33 - 2 = 31

• Rule = Here, the rule is we have to subtract each number by 2.

-------------------------

Given :

• 800,400,200,100,50

To find :

• Rule

Solution :

We see that,

800 ÷ 2 = 400

400 ÷ 2 = 200

200 ÷ 2 = 100

100 ÷ 2 = 50

• Rule = Here, the rule is we have to divide each number by 2.

-------------------------

Given :

• 55,45,35,25,15

To find :

• Rule

Solution :

We see that,

55 - 10 = 45

45 - 10 = 35

35 - 10 = 25

25 - 10 = 15

• Rule = Here, the rule is we have to subtract each number by 10.
