Question:

In the following question, select the missing number from the given series.

142, 150, 123, 187, 62, ?

Options:

1. 300
2. 285
3. 281
4. 278

Answer:

Option 4: 278

Explanation:

Let's analyze the series:

 * 142 + 8 = 150

 * 150 - 27 = 123

 * 123 + 64 = 187

 * 187 - 125 = 62

We can observe that the difference between consecutive numbers is increasing by 19 in each step.

So, the next difference should be 125 + 19 = 144.

Therefore, the missing number is 62 + 144 = 278.

Hence, Option 4 is the correct answer.
