Given the sequence: 155, 146, 137, 149, 140, 131, 143, 134, ...

What are the next two numbers in the sequence?

A. 125, 137
B. 124, 147
C. 134, 137
D. 136, 147
E. 136, 137

Answer :

To determine the next two numbers in the sequence, let's examine the pattern:

Given Sequence: 155, 146, 137, 149, 140, 131, 143, 134, ...

  1. Identify the Pattern:

    • Look at the differences between consecutive numbers:
      • 155 to 146: Decrease by 9
      • 146 to 137: Decrease by 9
      • 137 to 149: Increase by 12
      • 149 to 140: Decrease by 9
      • 140 to 131: Decrease by 9
      • 131 to 143: Increase by 12
      • 143 to 134: Decrease by 9
  2. Recognize the Alternating Pattern:

    • The differences alternate between decreasing by 9 and increasing by 12.
    • This suggests a recurring pattern of D9, D9, +12.
  3. Predict the Next Numbers Using the Pattern:

    • After 134, the pattern calls for a decrease by 9.

    \326134 - 9 = 125

    • Following that, the pattern calls for an increase by 12.

    \325125 + 12 = 137

  4. Conclusion:

    • The next two numbers in the sequence are 125 and 137.

Therefore, the correct option is A. 125, 137.
