Introduction

To complete a letter sequence series, you need to identify the rule or pattern governing the sequence.

Common patterns include arithmetic progressions, Alternating Sequences, and Interleaved Sequences.

For example, in the sequence AEH, BFI, CGJ, DHK, the pattern involves incrementing each letter by a fixed number of positions in the alphabet.

In the sequence B, D, G, J, L, the next letter could be determined by various patterns such as alternating differences or skipping consonants.

Possible answers for the next letter in the sequence B, D, G, J, L include N, M, O, or P, depending on the identified pattern.
Identifying Patterns [1]

Arithmetic Progression: A sequence where each term is obtained by adding a fixed number to the previous term.

Geometric Progression: A sequence where each term is obtained by multiplying the previous term by a fixed number.

Alternating Sequences: Sequences that alternate between different patterns or rules.

Interleaved Sequences: Sequences that combine two or more different sequences in an alternating manner.

Skipping Patterns: Sequences that skip certain letters or numbers based on a specific rule.
Common Sequence Types [1]

Arithmetic Sequences: Each term increases by a constant difference.

Geometric Sequences: Each term is multiplied by a constant factor.

Fibonacci Sequences: Each term is the sum of the two preceding terms.

Alphabetic Sequences: Sequences based on the position of letters in the alphabet.

Consonant/Vowel Sequences: Sequences that alternate between consonants and vowels.
Example Sequences [1]

AEH, BFI, CGJ, DHK: Increment each letter by a fixed number of positions.

B, D, G, J, L: Possible patterns include alternating differences or skipping consonants.

2, 4, 7, 10, 13: Convert letters to numbers and identify the pattern in the differences.

X, Y, Z, AA, BB: Alphabetic sequence continuing from the beginning after reaching Z.

B, E, H, K, N: Every 3rd letter in the alphabet.
Possible Solutions [1]

N: Every other consonant starting with B.

M: Pattern of skipped letters is 1  2  2  1.

O: Convert to integers and follow the pattern of differences.

P: Two interleaved sequences with different progressions.

L: Continue the pattern of differences and second differences.
Reasoning Techniques [1]

Identify the rule or pattern governing the sequence.

Convert letters to their numerical positions in the alphabet.

Analyze the differences between consecutive terms.

Consider multiple possible patterns and test each one.

Use logical reasoning to determine the most likely solution.
