Answer:

A. 66

Read Explanation:

1. The First Level of Differences

First, we look at how much each number grows to get to the next one:

  • From 3 to 10: +7

  • From 10 to 29: +19

At this stage, 7 and 19 don't show a clear pattern.


2. The Second Level of Differences

Now, we look at the difference between those gaps (7 and 19):

  • From 7 to 19: +12

In many series puzzles, the second level of differences follows a mathematical table (like the 6 times table: 6, 12, 18, 24...). Since the gap here is 12, the next gap in the sequence should be 18.


3. Working Backwards to Find the Answer

Now that we have identified the pattern (+6 for every new gap), we move back up:

  • Find the next First Difference:
    Take the previous difference (19) and add the new gap (18).
    19+18=3719 + 18 = \mathbf{37}

  • Find the next Number in the Series:
    Take the last number in your series (29) and add this new difference (37).
    29+37=6629 + 37 = \mathbf{66}
