Answer

To find the missing number in the series 14, 28, 42, 56, ?, 84, 98, we can follow these steps:

### Step 1: Identify the pattern in the series
The given series is: 14, 28, 42, 56, ?, 84, 98.

### Step 2: Check the differences between consecutive terms
- 28 - 14 = 14
- 42 - 28 = 14
- 56 - 42 = 14
- ? - 56 = ?
- 84 - ? = ?
- 98 - 84 = 14

From the calculations, we can see that each term is increasing by 14.

### Step 3: Calculate the missing term
Since the difference between each term is 14, we can find the missing term by adding 14 to the last known term before the missing one:
- 56 + 14 = 70

### Step 4: Verify the next term
Now, we can check if adding 14 to the missing term (70) gives us the next term:
- 70 + 14 = 84 (which is correct)

### Conclusion
Thus, the missing term in the series is **70**.

### Final Answer
The answer is **B. 70**.
