Select the ltter-cluster that can replace the question mark (?) in the given letter-cluster series. Study the given pattern carefully and select the number that can replace the question mark (?) in it. ? 8 11 7 6 5 48 63 72
- A.7
- B.4
- C.5
- D.6
Explanation
. The pattern is to add 1 to the number and then multiply the number we get, Column 2: (8 + 1) × (6 + 1) = 63 Column 3: (11 + 1) × (5 + 1) = 72 Column 1: (x + 1) × (7 + 1) = 48 → x + 1 = 6 → x = 5 Hence, 5 is the correct answer.
