Math Problem Statement

70, 74, 62, 50, 54, ..., ..., ..., 34. What are the missing numbers?

Solution

The sequence provided in the image is:

70,74,62,50,54,...,...,...,3470, 74, 62, 50, 54, ..., ..., ..., 34

The task is to determine the missing numbers and select the correct answer from the options provided.

Step-by-step Analysis:

  1. First two numbers: 70 → 74: The difference between the two numbers is +4.

  2. Second to third number: 74 → 62: The difference is -12.

  3. Third to fourth number: 62 → 50: The difference is -12.

  4. 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: 5412=4254 - 12 = 42
  • The sixth to seventh number: 42+4=4642 + 4 = 46
  • The seventh to eighth number: 4612=3446 - 12 = 34 (which is already given)

Thus, the missing numbers are 42,46,42, 46, and 3434.

Correct Answer:

The correct sequence is: 70,74,62,50,54,42,46,3470, 74, 62, 50, 54, 42, 46, 34.

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.
