Alphabet Series Logic

This question requires identifying the pattern in the given sequence of letters and determining the next letter based on that pattern.

Identifying the Pattern

  • The given series is A, D, G, J.
  • We need to find the relationship between consecutive letters. Let's look at their positions in the alphabet:
    • A is the $1^{st}$ letter.
    • D is the $4^{th}$ letter.
    • G is the $7^{th}$ letter.
    • J is the $10^{th}$ letter.
  • Calculate the difference in positions:
    • Position difference between D and A: $4 - 1 = 3$.
    • Position difference between G and D: $7 - 4 = 3$.
    • Position difference between J and G: $10 - 7 = 3$.
  • The pattern observed is that each subsequent letter is 3 positions after the previous letter in the alphabet.

Determining the Next Letter

  • The last letter given is J, which is the $10^{th}$ letter.
  • Applying the pattern, the position of the next letter will be the position of J plus 3: $10 + 3 = 13$.
  • The $13^{th}$ letter of the alphabet is M.

Therefore, the next letter in the series is M.
