The number 127 is a prime so can also be treated as the odd one of the series |

Kanu we are adding prime nos successively like 2, 3, 5, 7, 11 and no shoud be 13 not 12, b'coz 12 is not a prime no thats why 165 is a wrong no. |

125+2=127 127+3=130 130+5=135 135+7=142 142+11=153 153+13=166 but 165 is not a correct. So 165 is wrong answer. |

How we can know adding prime numbers only? |

Difference between successive numbers is in prime numbers increasing order such as 2, 3, 5, 7, 11, 13. Wrong number is 165. |

Hari said: (Jul 31, 2015) | |

The difference b/w each only prime numbers i, e; 2, 3, 5, 7, 11, 13, 17, 19, 23 etc, but in: 125+2=127. 127+3=130. 130+5=135. 135+7=142. 142+11=153. 153+13=166. But 165 is not a correct. So select 169. |

As per my logic, 153 will be the correct answer. |

How? @Kanhaiya. |

Nikhil Panwar said: (May 29, 2018) | |

Since, 127 is a prime number so take it out. |

9 is prime number so how can 11. |

Dipesh said: (Nov 5, 2019) | |

@Chekka 9 is not prime it is divisible by 3. |
