Question

A 729, G 343, _______, S 27

• A. N 225
• B. M 225
• C. M 125
• D. N 125

Answer 1

Answer:

C. M 125

The missing term that completes the pattern is M 125.

The series consists of two independent patterns combined together: one for the alphabetic letters and one for the numbers.

1. The Letter Pattern

Look at the positions of the letters in the English alphabet:

• A = 1st letter

• G = 7th letter (Increases by +6)

• ? = Should be the 13th letter (7 + 6 = 13), which is M

• S = 19th letter (13 + 6 = 19)

The letters increase sequentially by adding 6 positions each time, identifying the missing letter as M.

2. The Number Pattern

The numbers represent the cubes of decreasing odd numbers:

• $729 = 9^3$

• $343 = 7^3$

• ? = Should be $5^3 =$ 125

• $27 = 3^3$

The sequence uses the cubes of $9, 7, 5, 3$. Therefore, the missing value is $5^3 = 125$.

Combining both parts gives the final answer: M 125.
