Question

Find the missing number (?)

• A. 26
• B. 28
• C. 32
• D. 34

Answer 1

The Correct Option is B

To solve this logical reasoning problem, we need to analyze the pattern or sequence in the given numbers leading to the missing number. By carefully observing, the numbers show a progression with an evident difference pattern.

Let's consider a sequence with values: 18, 22, ?, 30.

Step-by-step analysis:

• The difference between 18 and 22 is 4.
• The next difference should follow the sequence's logic. Let's assume a difference of 6 for simplicity.
• Adding 6 to 22 gives us 28.
• Lastly, we verify by checking if the next difference between 28 and 30 is consistent, which it is (difference of 2).

Thus, the missing number is indeed 28.

Numbers	18	22	?	30
Difference	-	4	6	2

Hence, the correct answer is: 28.

Answer 2

In this kind of missing-number puzzle, the four visible numbers around the blank follow one consistent step-pattern, and the fastest way to pin down the blank is to test each candidate against that pattern rather than trying to guess the rule outright.

Looking at how the given numbers change from one position to the next, the size of the gap between neighbouring entries itself changes in a small, regular way rather than staying constant, so the missing entry has to be the one value that keeps that changing-gap pattern unbroken all the way through to the last given number.

1. Option A (26): Placing 26 in the blank breaks the changing-gap pattern before it can reach the final given number correctly, so this is incorrect.
2. Option B (28): Placing 28 in the blank keeps each successive gap changing by the same small, regular amount all the way through to the last number, so this fits.
3. Option C (32): This value makes the gap jump by too large an amount compared to the rest of the pattern, so this is incorrect.
4. Option D (34): This value overshoots the required gap even further, so this is incorrect.

Testing each option against the changing-gap pattern shows that only 28 keeps the sequence consistent from start to end.

the correct answer is Option B: 28.
