Last updated Aug 8, 2026
Correct Answer:
Option B —
J
The next letter in the sequence is J.To understand why, we look at the positions of each letter in the alphabet:
A is the 1st letter.
D is the 4th letter.
I is the 9th letter.
P is the 16th letter.
Y is the 25th letter.
The Pattern
The sequence follows the sequence of perfect squares:
1 times 1 is 1 (A)
2 times 2 is 4 (D)
3 times 3 is 9 (I)
4 times 4 is 16 (P)
5 times 5 is 25 (Y)
The next step is 6 times 6, which is 36.
Finding the Letter
Since the alphabet has only 26 letters, we wrap around to the beginning once we pass 26:
Subtract 26 from 36, which leaves 10.
The 10th letter of the alphabet is J.
