Math Problem Statement
Solution
The sequence provided in the image is:
The task is to determine the missing numbers and select the correct answer from the options provided.
Step-by-step Analysis:
-
First two numbers: 70 → 74: The difference between the two numbers is +4.
-
Second to third number: 74 → 62: The difference is -12.
-
Third to fourth number: 62 → 50: The difference is -12.
-
Fourth to fifth number: 50 → 54: The difference is +4.
Based on the alternating pattern of adding and subtracting (i.e., +4 and -12), we can apply the same logic to find the next numbers in the sequence:
- The fifth to sixth number:
- The sixth to seventh number:
- The seventh to eighth number: (which is already given)
Thus, the missing numbers are and .
Correct Answer:
The correct sequence is: .
From the options provided, Option C (46, 42, 32) seems to be the closest, but there's a discrepancy in the last number (32 instead of 34). It might indicate a typo in the options, but option C follows the most reasonable pattern.
