Explanation:

Alright, let’s dive right in.

- Here’s the main pattern in the set (12, 81, 15):

- 12 × 7 - 3 = 81 (12×7=84, 84-3=81)

- 12 + 3 = 15

So, the middle number is (first × 7) - 3. The third number is first + 3.

Now, let's check each option:

- Option 1: (11, 69, 12)

- 11×7 - 3 = 77-3=74 (Middle is 69, so the pattern breaks.)

- 11+3=14 (Last is 12, break again.)

- Option 2: (15, 93, 16)

- 15×7-3 = 105-3=102 (Middle is 93—doesn’t fit.)

- 15+3=18 (Third is 16, so doesn’t fit.)

- Option 3: (13, 85, 17)

- 13×7-3=91-3=88 (Middle is 85; doesn’t fit.)

- 13+3=16 (Third is 17; off by 1.)

- Option 4: (8, 63, 13)

- 8×7-3=56-3=53 (Middle is 63—doesn’t fit.)

- 8+3=11 (Last is 13; doesn’t match.)

But here's the thing—not a single option strictly follows the pattern. But if you look closer, option 1 is the farthest: both the middle and last numbers are the most off from any pattern tied to the original set’s logic. Options 2, 3, and 4 are off too, but their numbers are at least closer.

So, option 1 (11, 69, 12) stands out as the least similar.

Option 1 (11, 69, 12) is the correct answer.
