Choose one option.
Show answer & explanation
Answer: A. A) O16

The letter increments by 5 positions (E=5, J=10, O=15, T=20, Y=25) and the number increments by 5 (6, 11, 16, 21, 26), yielding O16.

Step-by-step Derivation:
Step 1: Letter series: E (5) + 5 = J (10); J (10) + 5 = O (15); O (15) + 5 = T (20); T (20) + 5 = Y (25).
Step 2: Number series: 6 + 5 = 11; 11 + 5 = 16; 16 + 5 = 21; 21 + 5 = 26.
Step 3: Combining letter and number gives O16.
