You are watching: What number is needed to complete the pattern below


66 73 13 21 52 __ 10 20

Method 1

Step 1

To find which number must finish the pattern, we have to observe the numbers and discover the pattern that was complied with in the series. With the assist of that pattern we can uncover the missing number.

We are going to give an X to the absyellowcomic.comt number:

66 73 13 21 52 X 10 20

Step 2

By observing the numbers we discover that the pattern is:

66 + 7 = 73

13 + 8 = 21

52 + ? = X

10 + 10 = 20

According to the pattern, the number to be included to 52 to obtain the lacking number X should be 9.

52 + 9 = X

X = 61

The number 61 is needed to finish the pattern.

Method 2

To find which number need to complete the pattern, we have to observe the numbers and find the pattern that was complied with in the series. With the assist of that pattern we deserve to discover the absyellowcomic.comt number.

Tip 1

The missing number is X

66 73 13 21 52 X 10 20

Tip 2

By observing the numbers we uncover that the pattern is:

73 – 66 = 7

21 – 13 = 8

X – 52 = ?


20 – 10 = 10

According to the pattern, the number that we obtained once we subtract 52 from X, have to be 9

X – 52 = 9

X = 9 + 52

X = 61

The number 61 is essyellowcomic.comtial to complete the pattern.

Q. 1 What number is required to finish the pattern below?

106 97 89 82 76 __ 67 64

Step 1

To find which number must finish the pattern, we need to observe the numbers and uncover the pattern that was complied with in the series. With the aid of that pattern we have the right to find the absyellowcomic.comt number.

The missing number is X

106 97 89 82 76 X 67 64

Tip 2

By observing the numbers we discover that the pattern is:

106 – 97 = 9

97 – 89 = 8

89 – 82 = 7

82 – 76 = 6

76 – X = ?

X – 67 = ??

67 – 64 = 3

According to the pattern, the number that we get whyellowcomic.com we subtract the lacking number X from 76, should be 5. Whyellowcomic.com we subtract 67 from the absyellowcomic.comt number X, should be 4.

76 – X = 5 and X – 67 = 4

X = 76 – 5 X = 67 + 4

X = 71 X = 71

The lacking number is 71.

The number 71 is necessary to finish the pattern.

Q.2 What number is necessary to finish the pattern below?

6 2 8 12 4 16 27 9 36 33 11 __

Step 1

To uncover which number have to finish the pattern, we need to observe the numbers and also find the pattern that was adhered to in the series. With the assist of that pattern we can discover the lacking number.

The lacking number is X:

6 2 8 12 4 16 27 9 36 33 11 X

Step 2

By observing the numbers we find that the pattern is:

6 + 2 = 8

12 + 4 = 16

27 + 9 = 36

33 + 11 = X

According to the pattern, 11 must be added to 33 to get the lacking number X.

33 + 11 = X

X = 44

The absyellowcomic.comt number is 44

The number 44 is essyellowcomic.comtial to finish the pattern.

Second method

To uncover which number must finish the pattern, we have to observe the numbers and uncover the pattern that was complied with in the series. With the assist of that pattern we deserve to uncover the missing number.

Step 1

The missing number is X:

6 2 8 12 4 16 27 9 36 33 11 X

Step 2

By observing the numbers we discover that the pattern is:

8 – 6 = 4


16 – 12 = 4

36 -27 = 9

X – 33 = 11

According to the pattern, 33 must be to subtracted from lacking number to get 11.

X – 33 = 11

X = 11 + 33

X = 44

The missing number is 44

The number 44 is essyellowcomic.comtial to finish the pattern.

Q.3 What number is necessary to finish the pattern below?

2 6 12 20 30 42 __

Tip 1

To uncover which number need to finish the pattern, we have to observe the numbers and also find the pattern that was complied with in the series. With the aid of that pattern we deserve to uncover the absyellowcomic.comt number.

The missing number is X:

2 6 12 20 30 42 X

Tip 2

By observing the numbers we discover that the pattern is:

6 – 2 = 4

12 – 6 = 6

20 – 12 = 8
