Correct:
A
Explanation
The given sequence is an interleaved series (also known as a twin series) where two different patterns alternate:
- Series 1 (Odd-positioned terms): 2, 4, 6, 8, 10, 12... This series follows a pattern of consecutive even numbers (or adding 2 to the previous term). The next term in this sequence (the 13th term) is 12 + 2 = 14.
- Series 2 (Even-positioned terms): 2, 3, 5, 7, 11, 13... This series follows the sequence of prime numbers in ascending order. The next prime number after 13 is 17.
By combining the next terms from both patterns, we get 14 and 17. Therefore, Option A is the correct answer.
