Question 1: Find the Missing Number in the Sequence

Year: 2010
Sequence:
6, 12, 18, ___, 30

Step-by-Step Reasoning:

This is a number pattern question, and we’re looking for the missing number between 18 and 30.

Let’s analyze the pattern:

• Step 1: Subtract the second number from the first:
  12 - 6 = 6
• Step 2: Check if the same difference continues:
  18 - 12 = 6
• This confirms the pattern is increasing by 6 each time. So:
• 18 + 6 = 24
• 24 + 6 = 30
• Final Answer: 24
