Understanding the Letter Series Pattern

The question presents a letter series: A, D, G, J, M, ?. We need to identify the pattern in this sequence of letters and find the missing term.

Letter series questions often involve patterns related to the position of letters in the English alphabet, skipping letters, or combinations of these.

Analyzing the Given Letter Sequence

Let's look at the position of each letter in the standard English alphabet:

Now, let's examine the difference between the positions of consecutive letters in the series:

• From A to D: Position increases from 1 to 4. Difference = \(4 - 1 = 3\).
• From D to G: Position increases from 4 to 7. Difference = \(7 - 4 = 3\).
• From G to J: Position increases from 7 to 10. Difference = \(10 - 7 = 3\).
• From J to M: Position increases from 10 to 13. Difference = \(13 - 10 = 3\).

Identifying the Series Rule

From the analysis above, it is clear that there is a consistent pattern in the series. Each subsequent letter is found by moving 3 positions forward in the alphabet from the previous letter. This means we are skipping two letters between each term (e.g., A -> B, C -> D).

Finding the Missing Term in the Series

To find the missing term after M, we need to apply the same rule. The position of M is 13. We need to move 3 positions forward from M.

New position = Position of M + 3 = \(13 + 3 = 16\).

The letter at the 16th position in the English alphabet is P.

Therefore, the missing term that completes the series A, D, G, J, M, ? is P.

Letter Series Completion Answer

The letter that completes the series is P.

Additional Information: Types of Letter Series

Letter series can follow various patterns. Some common types include:

• Alphabetical Order: Letters arranged sequentially or in reverse.
• Skipping Letters: Letters are selected by skipping a fixed or varying number of letters.
• Position-Based: Patterns related to the numerical position of letters (like in this question).
• Groupings: Letters arranged in groups with specific rules.
• Combined Patterns: A mix of numerical and alphabetical patterns.
• Reverse Order: Patterns based on the alphabet read backward (Z, Y, X...).

To solve letter series questions, it is helpful to know the position of each letter in the alphabet and practice identifying different types of patterns.
