Zorluk: OrtaNumber and Alphabet Series

A researcher is cataloging environmental samples using a specific alphabetical labeling sequence. The first five sample labels are assigned as follows:

BKR, EJU, IHY, NED, TAJ

If the labeling system continues with the exact same underlying logic, what will be the exact label for the next sample in the sequence?

  1. AVQCevap
  2. B
    AFQ
  3. C
    ZWP
  4. D
    WZM

Cevap

AVQ
The correct sequence combines three distinct rules running in parallel across the three letter positions. The first position moves forward in increasing steps (+3, +4, +5, +6, +7) ending at A. The second position moves backward in increasing steps (-1, -2, -3, -4, -5) ending at V. The third position moves forward in increasing steps (+3, +4, +5, +6, +7) ending at Q. Combining these yields the label AVQ.

Adım Adım Çözüm

1
Analyze the pattern of the first letter in each term: B, E, I, N, T.
The positional shifts are: B(+3) → E(+4) → I(+5) → N(+6) → T.
This establishes an increasing forward progression for the first position.
2
Calculate the next letter for the first position.
The next shift must be +7. T (20) + 7 = 27. Since the alphabet has 26 letters, 27 corresponds to A (1). The first letter is A.
Applying the established mathematical pattern to find the missing term.
3
Analyze the pattern of the second letter in each term: K, J, H, E, A.
The positional shifts are: K(-1) → J(-2) → H(-3) → E(-4) → A.
This establishes an increasing backward progression for the second position.
4
Calculate the next letter for the second position.
The next shift must be -5. A (1) - 5 = -4. Wrapping around the alphabet backwards (26 - 4) gives 22, which is V. The second letter is V.
Continuing the reverse alphabet indexing accurately.
5
Analyze the pattern of the third letter in each term: R, U, Y, D, J.
The positional shifts are: R(+3) → U(+4) → Y(+5) → D(+6) → J. (Note: Y(25)+5 = 30; 30-26 = 4 which is D).
This establishes an increasing forward progression for the third position.
6
Calculate the next letter for the third position.
The next shift must be +7. J (10) + 7 = 17. The 17th letter is Q. The third letter is Q.
Completing the final position using the deduced logical rule.
