Finding the Missing Number in the Series

Given series: 1, 9, 17, 33, 49, 73,...

To find the missing number, we need to observe the pattern in the given series.

Pattern in the Series

- The difference between the first and second terms is 8.
- The difference between the second and third terms is 8.
- The difference between the third and fourth terms is 16.
- The difference between the fourth and fifth terms is 16.
- The difference between the fifth and sixth terms is 24.

Thus, the pattern is not consistent. However, we can observe that the difference between the fourth and fifth terms is 16, which is twice the difference between the second and third terms.

Using this pattern, we can find the missing number as follows:

- The difference between the sixth and seventh terms should be 24 x 2 = 48.
- Adding 48 to the sixth term (73) gives us the missing number: 73 + 48 = 121.

Therefore, the missing number in the given series is 121.

Option D, which represents 97, is incorrect.
