Find the wrong number in the following number series 3, 7, 16, 35, 70, 153.
Answer & explanation
Correct answer: option 3
The series →
3 , 7 , 16 , 35 , 70 , 153
The pattern is,
3 , 3(2)+1 = 7 , 7(2)+2 = 16 , 16(2)+3 = 35 , 35(2)+4 ≠ 70
Here , fifth term breaks the rule , So wrong number in series is 70.
