Direction: In each of these questions a number series is given. Only one number is wrong in each series. You have to find out the wrong number.

  1. 2 , 3 , 11 , 38 ,102 , 229 , 443
    1. 11
    2. 229
    3. 120
    4. 38
    5. 3
Correct Option: B

The given series is in the below pattern,
First term = 2
Second term = First term + 13
Second term = 2 + 13 = 3 ;
Third term = Second term + 23
Third term = 3 + 23 = 11 ;
Similarly , we can find the all others terms also.
Fourth term = Third term + 42
Fourth term = 11 + 33 = 38 ;
Fifth term = Fourth term + 52
Fifth term = 38 + 43 = 102
Sixth term = Fifth term + 62
Sixth term = 102 + 53 = 229 ; 229 is wrong. It should be 227.
Seventh term = Sixth term + 72
Seventh term = 227 + 63 = 443
Hence, 229 is wrong. It should be 227.
