Question

What is the missing number in the sequence? 

 

• A. 49
• B. 50
• C. 60
• D. 69
• E.

Hint:

In sequential puzzles, carefully track the changes in values. Try checking increments or fixed differences.

Answer 1

The Correct Option is D

The pattern follows a simple addition sequence. The missing number is added in steps. 

Answer 2

Rather than describing the sequence in general terms, test each candidate by checking whether it keeps the growth pattern between consecutive terms of the figure consistent.

1. Option A (49): Slotting this value in breaks the steadily widening gap between consecutive terms that the rest of the sequence follows, so it does not fit.
2. Option B (50): This value is too close to the surrounding terms to preserve the increasing gap pattern seen across the rest of the sequence, so it is ruled out.
3. Option C (60): Though closer to the expected range, this value still does not keep the difference between consecutive terms growing at the same rate as the rest of the figure.
4. Option D (69): This is the only value that keeps the gap between consecutive terms growing at the same steady rate as every other step in the sequence, matching the pattern the figure establishes.

Hence, the missing number is 69.
