Correct Answer
A. 318Explanation
The given sequence follows a pattern where each number is obtained by multiplying the previous number by 3 and then subtracting 1. For example, 3 * 3 - 1 = 8, 8 * 3 - 1 = 23. However, the last number in the sequence does not follow this pattern. Therefore, the correct answer is 318, which is obtained by multiplying the previous number (171) by 3 and then subtracting 1.Rate this question:

Correct Answer
B. 61Explanation
The pattern in the given sequence is not immediately clear. However, upon closer inspection, we can see that each number in the sequence is obtained by adding the square of the position of the number in the sequence to the previous number. For example, 16 is obtained by adding the square of 2 (the position of 16 in the sequence) to 13. Similarly, 25 is obtained by adding the square of 3 to 16, and so on. Therefore, to find the missing number, we need to add the square of 5 to 40, resulting in 61.Rate this question:

Correct Answer
B. 11Explanation
The given sequence follows a pattern of increasing by 0.4, then increasing by 0.9, then increasing by 1.5, and so on. The difference between each term in the sequence is increasing by 0.5 each time. Therefore, to find the missing number, we add 0.4 to the last number in the sequence, which is 7.4. This gives us 7.8, which is not one of the options. However, if we continue the pattern and add 0.9 to 7.4, we get 8.3, which is also not one of the options. The next option, 11, is obtained by adding 1.5 to 7.4, which fits the pattern and completes the sequence.Rate this question:

Correct Answer
B. 147Explanation
The given sequence follows a pattern where each term is obtained by adding the square of the next odd number to the previous term. Starting with 3, we add the square of 3 (9) to get 12. Then, we add the square of 5 (25) to get 27, and so on. Continuing this pattern, we add the square of 13 (169) to 108 to get the missing term, which is 277. Therefore, the correct answer is 147.Rate this question:
