Study the provided matrix carefully and determine which number from the given options should replace the question mark (?).
13 | 4 | 165
11 | 7 | 114
15 | 3 | ?
Show answer & explanation
Correct answer: B
Explanation
The pattern followed in each row is:
(First number)2 − Second number = Third number
• Row 1: 132 − 4 = 169 − 4 = 165
• Row 2: 112 − 7 = 121 − 7 = 114
• Row 3: 152 − 3 = 225 − 3 = 222
Therefore, the missing number is 222.
