Find the missing number from the given alternatives.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 22
Going clockwise from the top, the numbers are 4, 6, 10, 14, ?, 26. Each is twice a prime number, and the primes come in order: 2, 3, 5, 7, ?, 13.

The prime between 7 and 13 is 11, so the missing number is \(2\times11=22\).
