Question

Complete the sequence: 24, __, 48, 63

• A. 35
• B. 14
• C. 37
• D. 39

Answer 1

The Correct Option is A

To solve the sequence: 24, __, 48, 63, we need to identify the logical pattern governing the progression of numbers.

1. Observe the difference between the known numbers in the sequence. We have 24 and 48 as consecutive numbers.
2. Find the difference between these two numbers: 48 - 24 = 24.
3. Next, examine the difference between 48 and 63: 63 - 48 = 15.
4. Notice that the difference between these consecutive terms decreases by 9 as we move forward:
   • The difference between the first and second term (i.e., unknown and 24) should logically be 24 - 9 = 15.
5. Thus, the second number can be calculated by: 24 + 15 = 39.
6. Therefore, the sequence continues correctly as 24, 39, 48, 63.

Based on this calculation, the correct option was considered to be 35. However, upon verifying using logical progression of decreasing differences by 9 each time, we conclude the correct answer should actually be 39. This anomaly suggests a need to revisit the structure of the original pattern or question details, if 35 is officially noted as correct.
