Question 1

Find the missing element (?) in this matrix pattern: A B C B C D C D ? What should replace the '?'?

Pattern: each cell is the next letter in alphabet from left/top

Step 1: Observe the pattern in first row: A → B → C (increment by 1)
Step 2: Second row: B → C → D (also increment by 1)
Step 3: Third row follows same pattern: C → D → ?
Step 4: Therefore, ? should be E (D + 1)
Pattern: Each row and column increases alphabetically by 1 position
