12

The given sequence of numbers is 21, 20, 14, 12. The pattern in the sequence is that each number is decreasing by a certain amount. Specifically, the first number decreases by 1, the second number decreases by 6, and the third number decreases by 2. Therefore, the next number in the sequence should decrease by 1, resulting in the number 12.

Explanation

The given sequence of numbers is 21, 20, 14, 12. The pattern in the sequence is that each number is decreasing by a certain amount. Specifically, the first number decreases by 1, the second number decreases by 6, and the third number decreases by 2. Therefore, the next number in the sequence should decrease by 1, resulting in the number 12.

6) Seventy

17

70

77

75

The number 70 is the only one that can be formed by combining the digits of the other numbers. By taking the first digit of 17 (1) and the second digit of 77 (7), we get 17. By taking the first digit of 70 (7) and the second digit of 75 (5), we get 75. However, by taking the first digit of 70 (7) and the second digit of 17 (7), we get 77. Therefore, the only number that cannot be formed by combining the digits of the other numbers is 70.

Therefore, the only number that cannot be formed by combining the digits of the other numbers is 70.

7) 2, 4, ......., 8, 10

5

6

7

9

The given sequence starts with 2 and increments by 2 each time. Therefore, the missing number should be the next number in the pattern, which is 6.

Explanation

The given sequence starts with 2 and increments by 2 each time. Therefore, the missing number should be the next number in the pattern, which is 6.

8) 7, 14, ......., 28, 35

21

22

23

24

The given sequence starts with 7 and increases by 7 each time. So, the next number would be 21, followed by 28 and then 35. Therefore, the correct answer is 21.

Explanation

The given sequence starts with 7 and increases by 7 each time. So, the next number would be 21, followed by 28 and then 35. Therefore, the correct answer is 21.

9) B) tick the given number in words. 5 Eighty- nine

79

59

89

69

The correct answer is 89 because it is the only number that matches the given number in words, which is "Eighty-nine".

Explanation

The correct answer is 89 because it is the only number that matches the given number in words, which is "Eighty-nine".

11) 4, 8, 12, ......, 20

15

16

17

18

The given sequence starts with 4 and increases by 4 each time. So, the next number in the sequence would be 16.

Explanation

The given sequence starts with 4 and increases by 4 each time. So, the next number in the sequence would be 16.

12) 6, 12, 18,. ........, 30

19

20

22

24

The given sequence is formed by adding 6 to each previous number. Starting with 6, we add 6 to get 12, then add 6 again to get 18. Continuing this pattern, we add 6 to 18 to get 24. Therefore, the missing number in the sequence is 24.

Explanation

The given sequence is formed by adding 6 to each previous number. Starting with 6, we add 6 to get 12, then add 6 again to get 18. Continuing this pattern, we add 6 to 18 to get 24. Therefore, the missing number in the sequence is 24.
