Correct Answer & Explanation
Option D
Each term is a multiple of 4 with a prime factor:
28 = 4 × 7
44 = 4 × 11
68 = 4 × 17
80 = 4 × 20 (20 is not a prime number)
92 = 4 × 23
• The numbers multiplied by 4 are consecutive primes (7, 11, 17, 19 would give 76, 23). Since 20 is composite, 80 is the wrong/inconsistent term.
