Identify the missing term in the alphanumeric pattern: A1Z, C3X, E5V, G7T, ...?

Answer and explanation

Correct answer: B. I9R

  1. Step 1: Analyze each component across terms:
  2. Step 2: First letter: A (1), C (3), E (5), G (7) -> skips one letter, next is I (9).
  3. Step 3: Number: 1, 3, 5, 7 -> odd integers, next is 9.
  4. Step 4: Third letter: Z (26), X (24), V (22), T (20) -> decreases by 2 letters, next is R (18).
  5. Step 5: Combine components: I9R.
Answer
I9R.
Why not the others: 'I9S' decrements the last letter by 1 instead of 2; 'H8R' advances letters by 1 step instead of 2; 'J9Q' uses an incorrect first letter.
