A. 15Explanation
The series alternates between adding 1 and adding 3. The pattern is +1, +3, +1, +3, and so on. Starting with 3, the next number should be 4+1=5, then 5+3=8, then 8+1=9, and so on. Therefore, the next number in the series should be 12+3=15.Rate this question:

Correct Answer
A. 211Explanation
The series follows a pattern of adding 1, then 2, then 3, and so on. Starting with 201, we add 1 to get 202, then add 2 to get 204, then add 3 to get 207. The next number in the series should be obtained by adding 4 to the previous number, which gives us 211.Rate this question:

58
Correct Answer
A. 56Explanation
The series alternates between doubling the previous number and subtracting 8. Starting with 14, the next number is obtained by doubling 14 to get 28. Then, subtracting 8 from 28 gives 20. Continuing this pattern, the next number is obtained by doubling 20 to get 40, and then subtracting 8 to get 32. Therefore, the next number in the series should be 64.Rate this question:

Correct Answer
A. 4.7Explanation
The series follows a pattern where each number is obtained by adding 0.8 to the previous number. Starting with 1.5, we add 0.8 to get 2.3, then 0.8 again to get 3.1, and so on. Therefore, the next number in the series should be obtained by adding 0.8 to the previous number, which gives us 3.9 + 0.8 = 4.7.Rate this question:

Correct Answer
A. 8Explanation
The pattern in the series is that each number is divided by 5 to get the next number. Starting with 1000, when we divide it by 5, we get 200. Then, when we divide 200 by 5, we get 40. Therefore, the next number in the series should be 40 divided by 5, which is 8.Rate this question:

20
Correct Answer
A. 20Explanation
The pattern in the series is that the first number is subtracted by 10, and the second number is added by 5. This pattern alternates for each pair of numbers. So, starting with 80, we subtract 10 to get 70, then add 5 to get 75. Continuing this pattern, we subtract 10 from 75 to get 65, then add 5 to get 70. Therefore, the next number in the series should be 20, as we subtract 10 from 70.Rate this question:

Correct Answer
A. 3.6Explanation
The pattern in the series is that each number is decreasing by 0.4. Starting from 5.2, each subsequent number is 0.4 less than the previous number. Therefore, the next number in the series should be 3.6, as it is 0.4 less than 4.Rate this question:
