Find the next term of the following letter series: AZ, GT, MN, SH, ?

Question

Accepted Answer

To determine the next term in the letter series AZ, GT, MN, SH, we need to identify the pattern in the sequence.

1. **Analyzing the Pattern:**
   - The series consists of pairs of letters.
   - Let's break down the pattern by examining the positions of the letters in the alphabet.

**First Letters:**
   - A (1st letter), G (7th letter), M (13th letter), S (19th letter)
   - The pattern here is an increment of 6: A + 6 = G, G + 6 = M, M + 6 = S.
   - Continuing this pattern, the next letter should be S + 6 = Y (25th letter).

**Second Letters:**
   - Z (26th letter), T (20th letter), N (14th letter), H (8th letter)
   - The pattern here is a decrement of 6: Z - 6 = T, T - 6 = N, N - 6 = H.
   - Continuing this pattern, the next letter should be H - 6 = B (2nd letter).

2. **Constructing the Next Term:**
   - Based on the identified patterns, the next term in the series should be YB.

3. **Explanation of Options:**
   - **Option 1: YC** - Incorrect because the second letter does not follow the decrement pattern.
   - **Option 2: ZC** - Incorrect because neither letter follows the identified pattern.
   - **Option 3: ZB** - Incorrect because the first letter does not follow the increment pattern.
   - **Option 4: YB** - Correct because both letters follow the identified patterns: Y follows the increment of 6 from S, and B follows the decrement of 6 from H.

Therefore, the correct answer is Option 4: YB. This option correctly follows the established pattern in the series, making it the logical continuation of the sequence.
