Rules or steps to find the missing number in series

To find a missing counting number in a series, we need to follow these steps:

Suppose we have the following sequence: 3, 6, 9, __, 15.

Step 1: Determine the order of the series. We can see that the numbers in the sequence are increasing from left to right, so the order is ascending.

Step 2: Find the difference between the numbers. We need to find the difference between each pair of adjacent numbers. In this case, the difference between each number is 3, since 6 - 3 = 3, 9 - 6 = 3, and 15 - 12 = 3.

Step 3: Use the difference to find the missing number. Since the order of the sequence is ascending, we add the difference to the last number in the sequence to find the missing number. Therefore, the missing number is: The last number in sequence + difference = 15 + 3 = 18

So, the missing number is 18, and the sequence becomes 3, 6, 9, 12, and 15.

- A. 38
- B. 68
- C. 78
- D. 98

B. 68

**Answer**: The missing number is 68.

**Explanation:**

We can observe that each number in the series is increasing by 20. Therefore, to find the missing number, we need to add 20 to the previous number, which is 48.

48 + 20 = 68

Hence, the missing number in the series is 68.

Therefore, the answer is option B. 68.
