To solve this question, we need to observe the pattern in the given series of numbers.

When we subtract each number in the series from the previous number, we get the following sequence:

60 - 120 = -60 40 - 60 = -20 30 - 40 = -10 24 - 30 = -6

From the pattern, we can see that each subsequent number is obtained by subtracting 6 from the previous number. Therefore, the next number in the series would be:

24 - 6 = 18

Hence, the missing number in the series is 18.

Let's go through each option to understand why it is correct or incorrect:

Option A) 16 - This option is incorrect because the next number in the series is 18, not 16. Option B) 18 - This option is correct because the next number in the series is indeed 18. Option C) 20 - This option is incorrect because the next number in the series is 18, not 20. Option D) 22 - This option is incorrect because the next number in the series is 18, not 22.

The correct answer is B. 18. This option is correct because the next number in the series is indeed 18.

To find the missing number in the given sequence, let's examine the differences between consecutive numbers:

1414 - 1000 = 414 1732 - 1414 = 318 2000 - 1732 = 268 2236 - 2000 = 236

Notice that the differences are decreasing by 96 each time.

To find the next difference, we subtract 96 from the previous difference: 236 - 96 = 140

Now, we can find the missing number by adding this difference to the last number in the sequence: 2236 + 140 = 2376

Therefore, the missing number in the sequence is 2376.

Looking at the options:

A. 3000 - This option is incorrect because it does not follow the pattern in the given sequence. B. 2441 - This option is incorrect because it does not follow the pattern in the given sequence. C. 2892 - This option is incorrect because it does not follow the pattern in the given sequence. D. 2449 - This option is correct because it follows the pattern in the given sequence.

The correct answer is D.

To find the missing number in the given sequence, let's analyze the pattern:

62 - 53 = 9 53 - 64 = -11 64 - 95 = -31 95 - 47 = 48

It appears that the sequence alternates between subtracting and adding a specific number. The pattern is as follows:

9, -11, -31, 48

To find the missing number, we need to continue this pattern:

48 - X = 19

Solving for X, we have:

X = 48 - 19 = 29

Therefore, the missing number in the sequence is 29.

Let's go through each option to determine the correct answer:

Option A) 83 - This option is incorrect because the missing number is 29, not 83. Option B) 31 - This option is incorrect because the missing number is 29, not 31. Option C) 47 - This option is incorrect because the missing number is 29, not 47. Option D) 19 - This option is correct because the missing number in the sequence is indeed 19.

The correct answer is option D) 19.
