In each of the following questions, a group of three numbers/symbols is given in each option. Identify the group that does NOT follow the same pattern as the others.

AK11 : I9 : G7

BM13 : K11 : I9

CO15 : M13 : K11

DN14 : K11 : H8

Answer:

D. N14 : K11 : H8

Read Explanation:

Check the pattern in each group:

1. K11 : I9 : G7
K(11), I(9), G(7) → letters and numbers both decrease by 2

2. M13 : K11 : I9
M(13), K(11), I(9) → same pattern (−2 each step)

3. O15 : M13 : K11
O(15), M(13), K(11) → same pattern (−2 each step)

4. N14 : K11 : H8
N(14), K(11), H(8) → decreases by 3, not 2

So this one does NOT follow the pattern.

Answer: N14 : K11 : H8
