Zorluk: KolayNumber and Alphabet Series

Consider the following alphabetical sequence:

C,F,I,L,…C, F, I, L, \dots

Which letter completes the given series?

  1. OCevap
  2. B
    N
  3. C
    P
  4. D
    M

Cevap

The letter that completes the series is O.
Each letter advances by 3 positions in forward alphabetical order: C (3) → F (6) → I (9) → L (12). Adding 3 positions to 12 gives 15, which corresponds to the letter O.

Adım Adım Çözüm

1
Determine the numerical positions of each letter in the standard alphabet.
C = 3, F = 6, I = 9, L = 12.
Translating letters to positional values simplifies pattern identification.
2
Identify the pattern of position shifts between consecutive terms.
6 - 3 = 3; 9 - 6 = 3; 12 - 9 = 3. Each term increases by +3 positions.
Finding the consistent rule enables calculating the next term.
3
Apply the rule (+3 positions) to the last given letter L (12).
12 + 3 = 15, which corresponds to the letter O.
Adding the common difference yields the next alphabetical term.
