Solving the Letter Sequence Puzzle: AD CG FK JP

The question asks to find the next term in the given sequence: AD CG FK JP. We need to identify the pattern governing the sequence.

Identifying the Pattern

Let's analyze the sequence by considering the first and second letters separately. We will use the standard alphabetical positions (A=1, B=2, ..., Z=26).

Analyzing First Letters

The first letters of the terms are A, C, F, J.

• A is the $1^{st}$ letter.
• C is the $3^{rd}$ letter. (Difference from A: $3 - 1 = 2$)
• F is the $6^{th}$ letter. (Difference from C: $6 - 3 = 3$)
• J is the $10^{th}$ letter. (Difference from F: $10 - 6 = 4$)

The differences between consecutive first letters are increasing by 1: 2, 3, 4. The next difference should be $4 + 1 = 5$. Therefore, the next first letter will be the $10 + 5 = 15^{th}$ letter of the alphabet, which is O.

Analyzing Second Letters

The second letters of the terms are D, G, K, P.

• D is the $4^{th}$ letter.
• G is the $7^{th}$ letter. (Difference from D: $7 - 4 = 3$)
• K is the $11^{th}$ letter. (Difference from G: $11 - 7 = 4$)
• P is the $16^{th}$ letter. (Difference from K: $16 - 11 = 5$)

The differences between consecutive second letters are also increasing by 1: 3, 4, 5. The next difference should be $5 + 1 = 6$. Therefore, the next second letter will be the $16 + 6 = 22^{nd}$ letter of the alphabet, which is V.

Determining the Next Term

Combining the next first letter (O) and the next second letter (V), the next term in the sequence is OV.
