Attempted by 67 students.
Show answer & explanation
Correct answer: D
Observe the pattern of subtraction: 325 − 66 = 259
259 − 55 = 204
204 − 44 = 160
160 − 33 = 127 (but given 125) ❌
127 − 22 = 105
105 − 11 = 94
The pattern is subtraction of decreasing multiples of 11 : 66, 55, 44, 33, 22, 11 So, 125 breaks the pattern. It should be 127 . 👉 Wrong term = 125
