Question

Based on the English alphabetical order, three of the following four letter-clusters are alike in a certain way and thus form a group. Which letter-cluster DOES NOT belong to that group? (Note: The odd one out is not based on the number of consonants/vowels or their position in the letter-cluster.)

• A. GKI
• B. MQO
• C. SWU
• D. KON

Answer 1

Answer:

D. KON

Letter-clusters: GKI, MQO, SWU, KON

We are not looking at vowels/consonants, just the alphabetical pattern. Let’s examine the difference between consecutive letters in each cluster.

1️⃣ GKI

Positions in alphabet:

• G = 7, K = 11, I = 9

• Differences:

  • K − G = 11 − 7 = +4

  • I − K = 9 − 11 = −2

---

2️⃣ MQO

• M = 13, Q = 17, O = 15

• Differences:

  • Q − M = 17 − 13 = +4

  • O − Q = 15 − 17 = −2

Same pattern as GKI: +4, −2

3️⃣ SWU

• S = 19, W = 23, U = 21

• Differences:

  • W − S = 23 − 19 = +4

  • U − W = 21 − 23 = −2

Same pattern: +4, −2

4️⃣ KON

• K = 11, O = 15, N = 14

• Differences:

  • O − K = 15 − 11 = +4

  • N − O = 14 − 15 = −1

Pattern is +4, −1, not +4, −2

---

KON does not belong to the group.
